DETAILED HISTORY OF OPENDOORS EVOLUTION
---------------------------------------
VERSION 1.00 Initial beta test version of the OpenDoors doordriver. Proved to
be very bug-free.
VERSION 1.10 First public release.
VERSION 1.20 Made several changes:
- Support for the new RemoteAccess 1.00 enhanced
exitinfo.bbs file, with many extra pieces of information.
- Added a Alt-K function key to allow the sysop to
temporarily disable the user's keyboard
- Added full support for turning on and off status line.
Status line has been changed slightly in format, and [F9]
help function key added.
- Improved sysop chat mode (added multi-colour and wordwrap)
- Fixed up shell-to-DOS to automatically shell to the
command processor specified in COMSPEC instead of always
using COMMAND.COM. OpenDoors now also returns to system to
the drive and directory it was in before DOS shell was
issued.
- Added support for the new RemoteAccess "sysop next" key.
VERSION 1.30 A few quick changes to perfect all the features of this version
before beginning major development work on OpenDoors 2.00. Fixed
two problems:
- The status line can no longer be turned back on by the
sysop using F1 - F9 keys when a door program has disable
the status line itself.
- A rather major problem was fixed for use of OpenDoors in
conjunction with RA 1.00. We accidentally forgot to save
some of the data that is unused in previous versions, but
is now used in the new version. This bug caused some
unexpected problems, including damage to the USERSXI.BBS
file.
VERSION 1.40 Another maintenance release. This version should now function
perfectly when used in conjunction with older versions of Turbo
C. Other changes in this version include:
- Better error recovery in the case that the door
information file has been damaged.
- OpenDoors was made more customizable, including allowing
the programmer to alter the various OpenDoors messages,
and provisions for user defined function keys for the
sysop. (ie, it is now possible for the programmer to make
Alt-Y another hotkey for the sysop)
VERSION 2.00 Another release, adding a number of new features, such as:
- Added support for AVATAR graphics. OpenDoors will
automatically detect the presence of AVATAR graphics mode
when running under Remote Access, and will allow your door
to toggle it when running under other BBS systems.
- Improved ANSI routines. Added some new functions, and
changed existing functions to send more efficient ANSI
codes in some circumstances.
- The "Sysop Next" key should now work correctly with RA
1.00 and later.
VERSION 2.10 Changes in this version include:
- Implementation of a registration key-code to allow
registered users to more easily upgrade to new versions.
- Added an od_printf() function for ease of formatted output
from within OpenDoors.
VERSION 2.20 More improvements, including:
- Fixing of some minor bugs, such as incorrect handling of
the path to DORINFO1.DEF/EXITINFO.BBS files.
- Added support for more customization, such as hooks for
functions that will be called before and after Shell to
DOS and sysop chat.
- OpenDoors is now DesqView aware. OpenDoors will
automatically detect the presence of DesqView, and uses
the DesqView `virtual screen buffer' for screen display if
present.
- A QuickBBS 2.75 compatibility problem has also been fixed.
VERSION 2.30 Fixed a small bug in the registration system.
VERSION 3.00 A major upgrade, released as a beta-test version, including the
following additions/changes:
- Eliminated many bugs.
- Added support for door information files from: WWIV, PC-
Board, Spitfire, WildCat, GAP, TriTel and others.
- Added .ASC/.ANS/.AVT file display support with automatic
interpretation of QBBS/SuperBBS/RA control characters.
- Added ALT-D key to drop the user back to the BBS without
hanging up.
- Added direct access to RA style configuration, file area,
message area, external protocols, event configuration,
caller history, users online, menu files, user base and
other system files.
- Added complete set of message base manipulation routines,
with full support for the RA 1.01 message base locking
scheme.
- The user manual has also been re-written in order to make
it easier to work with.
VERSION 3.10 The following bug fixes and changes have been made since the
release of the beta version, 3.00:
- Time fields in messages are now correctly formatted
- Corrected a bug in the od_set_attrib function where the
intensity setting would not correctly be transmitted to
the remote when using ANSI graphics.
- Fixed a bug in the re-writing of the DORINFO1.DEF which
cause sysop and user's last names to be corrupted.
- Registered users may now disable the display of copyright
and registration information when the door starts up.
VERSION 3.20 A few more changes and bug fixes were made since version 3.10,
including:
- Fixed the FILES.BBS lister to correctly support FILES.BBS
files located in directories other than the default dir,
and added page pausing to the FILES.BBS lister.
VERSION 3.30 The following changes and bug fixes were made since version 3.20:
- OpenDoors no longer re-writes the DORINFO1.DEF upon
exiting. No BBS's are known to actually make use of the
information changed in DORINFO1.DEF, and re-writing this
file was causing more troubles than it was worth.
- The od_msg_read_hdr() function's NEXT_MESSAGE command now
works correctly.
- Added an od_errno variable to assist in debugging of
programs written with the BBS file engine portion of
OpenDoors.
VERSION 3.40 A minor upgrade version, with the following changes:
- Fixed a compatibility problem with some locked baud rates.
Now, if OpenDoors receives a baud rate the door
information file that is not supported in the FOSSIL
definitions, it will continue without setting the baud
rate. (Whereas before, OpenDoors would report an error and
exit.)
- Made some changes to the manual, and included a utility to
remove the extended-ASCII characters from the manual to
ease printing on some printers.
VERSION 4.00 This version is a major overhaul of the entire OpenDoors package,
including a great many enhancements and additions. As of version
4.00, OpenDoors is available as two separate packages - the door
programming toolkit (this package), and the BBS interface package
(which is available separately) Among the major changes to
version 4.00 of the OpenDoors door programming toolkit are:
- A complete re-organization of the manual, including the
re-writing of a large portion of the manual. In order to
ease printing on some printers, the manual has been re-
formatted in order that it no longer contains extended
ASCII characters. More thorough documentation on the
OpenDoors functions and structures was written, along with
the addition of many more examples. Also added to the
manual are an index, glossary and other features intended
to make the reference manual an even more powerful and
flexible tool.
- Full support for the changes to RemoteAccess 1.10/1.11 has
been added for version 4.00. These include the addition of
some new fields stored in the EXITINFO.BBS door
information file, and proper adjusting of the user's time
remaining online. Version 4.00 also now has full support
for the new QuickBBS-specific EXITINFO.BBS file.
- All of the text displayed by OpenDoors is now fully
customizable using od_control structure variables. This
permits both greater door customization, and adds the
ability to write 100% non-English doors and programs.
- The OpenDoors status lines have been changed. OpenDoors
now provides additional user information through multiple
RemoteAccess-style status lines, accessible through the
F2, F3, etc. keys. Also, the status line may now be turned
off by using the F10 key, allowing the sysop to view all
25-lines of the information displayed by a door program. A
new function od_set_statusline(), permits program
selection of the current status line setting.
- OpenDoors now allows colour codes to be embedded in
od_printf() functions, to eliminate the need for long
chains of alternating od_disp_str(), od_set_colour() /
od_set_attrib() function calls.
- A new formatted input function, od_edit_str() has been
added for use in door programs running in ANSI or AVATAR
graphics mode. The od_edit_str() function features
advanced line editing capabilities which are normally
found only in non-door programs, such as inserting or
deleting text from the middle of a string, moving the
cursor with the arrow keys, and so on. The od_edit_str()
function also provides input formatting, allowing you to
force the user's input into any format you wish, from
phone number formats to date formats to username formats.
The od_edit_str() also provides special modes for
implementing features such as password input, field input
(where the user may move from one field to another using
arrow/tab keys), input field highlighting, editing
existing strings, auto-delete, and much more. The old
od_input_str() function still provides a subset of these
features which do not require ANSI or AVATAR graphics.
- New functions have been added to the door driver module of
OpenDoors. Among these, are an od_putch() function for
displaying one character at a time, and an od_spawn()
function, for easily executing other programs from within
OpenDoors. The od_spawn() function automatically saves the
contents of the current door screen, system drive and
directory, and provides a separate screen on which the
spawned-to program can execute. The od_draw_box() function
allows you to easily display windows in door programs,
using ANSI or AVATAR graphics codes. Also added is are
od_carrier(), od_set_statusline() and od_edit_str()
functions, mentioned elsewhere.
- More changes have been made in order to permit greater
customization and flexibility of OpenDoors. An
od_carrier() function has been added to detect the state
of the carrier detect signal in programs that disable
OpenDoor's internal carrier detection. Also, it is now
possible to shut down OpenDoors without exiting via the
od_exit() function.
- OpenDoors now yeilds the processor to other executing
tasks in multitasking environments (ie. DesqView), when
the door is inactive or waiting for input.
- The door driver function od_clr_scr() now only checks the
user's screen clearing setting if that information is
available from the door information file. If the
information is not available, the od_clr_scr() function
will always clear the screen.
- Many other small changes were also made for version 4.00.
Among these, you now have access to the user's reason for
chat and you can switch the pause and stop keys on and off
during listing of available files or displaying a text
file. Also, previous versions of OpenDoors would read the
user's information from the first door information file
found. Instead, version 4.00 now reads the most recently
created door information file. A bug in the od_clr_line()
function has also been fixed.
VERSION 4.10 A great deal of work has been done between version 4.00 and 4.10
of OpenDoors. This work falls into three major categories: bug
fixes, improved performance, and new features. In fact, enough
changes and improvements have been made that this version really
ought to be numbered 5.00. Below is a summary of the changes that
have occurred since version 4.00:
- Much of the door information file interfacing code has
been revamped, in order that OpenDoors now works correctly
with the newest versions of the BBS packages it supports.
OpenDoors now differentiates between three different
DOOR.SYS formats - the DoorWay format, the PC-Board / GAP
format, and the Wildcat format. Also, the SFDOORS.DAT code
has been fixed to correctly work with the newest version
of Spitfire.
- OpenDoors will now attempt to swap itself and your entire
door program to expanded memory or disk when the sysop
shells to DOS, or when you call one of the od_spawn...()
functions. Memory swapping may be configured in a number
of ways, or even disabled. The OpenDoors swapping code
adds only 2K to the door's .EXE file size.
- OpenDoors now includes a new od_spawnvpe() function. In
addition to the features of the "quick-spawn" od_spawn()
function, od_spawnvpe() also returns the errorlevel the
called program returned, allows you to alter the
environment passed to the child process, and uses the same
parameter format as the C spawnvpe() function. (see page
117)
- The od_page() function now checks the sysop paging hours,
set in the OpenDoors control structure. If the user
attempts to page the sysop outside of the defined paging
hours, he or she will be notified that the sysop is not
available.
- OpenDoors now includes a configuration file sub-system
that you may choose to include in your OpenDoors programs.
This sub-system automatically parses the configuration
file you specify, responding to any of the built-in
configuration commands, and passing configuration options
specific to your program back to you. With only a single
line of code on your part, this sub-system will allow
people running your program to configure many options such
as sysop paging hours, system directories, maximum time
within the door, etc. It also allows the sysop to provide
information that may not be supplied by their particular
BBS software, such as modem settings, the system's name
and so on. In addition to all these built in commands, you
can add your own configuration options, such as display
colours, registration key numbers and other information
needed by your program - without the need to write your
own configuration file parsing routines. (See page 76)
- OpenDoors now supports custom, sysop-defined door
information file (drop file) formats. By defining a custom
door information file format in the cofiguration file,
OpenDoors door programs can now be made to run directly
under BBS packages that use proprietary file formats that
are not directly supported by OpenDoors. (see page 78)
- In order to make doors written with OpenDoors even more
foolproof for the sysop to setup, an intelligent door
information file (drop file) locator has been added.
OpenDoors will automatically search for a door information
file in the directory specified by the configuration file,
the directory specified by your door's source code, the
current directory, and the directory pointed to by the
environment variables used by any of a number of BBS
packages.
- OpenDoors now includes a log file sub-system that you may
choose to include in your programs. The log file system
handles all access and formatting of the logfile, allowing
the programmer to make log file entries by simple function
calls such as od_write_log("User downloading file");.
Also, since the log file system is closely integrated with
the rest of OpenDoors, choosing to include the logfile
system in a program causes OpenDoors to automatically
output the most common logfile entries for events such as
the user paging sysop, the user hanging up, sysop chatting
with the user, user inactivity timeouts, and so on. (see
page 89)
- OpenDoors 4.00 would not always correctly turn on and off
high intensity or flashing colour attributes in ANSI mode.
The ANSI colour handling code has been reworked for
version 4.10, to eliminate these problems.
- An od_get_answer() function has been added, which can be
used to easily permit only certain keys to be pressed in
response to a prompt. For instance, to get a Yes/No
response from the user, use od_get_answer("YN"); (see page
66)
- A popular addition to OpenDoors 4.00 was the ability to
change the current display colour within od_printf()
format strings, using imbedded control characters.
However, the programmer was forced to use a rather cryptic
two-byte control sequence, where the second character of
the sequence contained an 8-bit colour attribute value. It
is now possible to change the display colour within
od_printf() by specifying the names of the desired
foreground and background colours, delimited by a set of
BACK-QUOTE (`) characters. For example:
od_printf("`Red` THIS TEXT IS RED `Blue` THIS TEXT IS BLUE");
od_printf("`Flashing bright green on dark green` AND THIS IS GREEN");
(see page 93)
- Version 4.10 would not correctly "freeze" the user's time
during DOS shell and sysop page operations, when the door
was operating under RemoteAccess 1.11. This has been
fixed.
- A new variable, od_spawn_freeze_time, has been added to
the OpenDoors control structure. When set to FALSE, the
user's time remaining continues to be deducted during the
execution of any of the od_spawn... functions. When set to
TRUE, the user's time remaining is frozen during the
execution of an od_spawn... function.
- The current directory is now correctly restored to its
original setting after the sysop returns from a DOS shell,
and after calls to the od_spawn... functions.
- A number of people were experiencing difficulty using the
od_edit_str() function in version 4.00. A number of
improvements to this function's logic have been made in an
attempt to make od_edit_str() more foolproof to use. Also,
a new flag setting, EDIT_FLAG_LEAVE_BLANK has been added.
However, there were a few reports of problems which we
were not able to reproduce. If you are still having
difficulty with this function, please carefully re-read
the section of the manual pertaining to it's use. In
particular, be sure that your difficulty is not resulting
from the flag settings you are using. If you still suspect
a bug in this function, please include with your bug
report the source code that is causing the problem.
- Page pausing within the od_send_file() and od_list_files()
(FILES.BBS listing routine) functions can now be disabled
and re-enabled by the programmer.
- The "Continue? [Y/n/=]" end of screen prompt and response
keys are now fully customizable.
- The od_list_files() FILES.BBS listing function now works
correctly in all memory models. The function has also been
fixed to correctly handle cases where the trailing
backslash is not supplied in the path parameter.
- The actual BBS line (node) number is now displayed on the
default status line, provided that this information is
supplied by the BBS software.
- It is now possible to detect whether keystrokes originated
from the remote or local keyboard. This is a feature that
is useful in some special applications, such as split-
screen sysop chat programs.
- Version 4.00 would not always correctly display the status
lines, if there was information missing from the
EXITINFO.BBS file. This has been fixed. In addition, the
"next event" information is now correctly displayed on the
status lines. Also, if the user's birthday is available,
their age will also be calculated and displayed on the
status line.
- If you temporarily disable inactivity timeouts, OpenDoors
will no longer automatically trigger and inactivity
timeout as soon as you re-enable this feature.
- A new function, od_hotkey_menu(), has been added to
facilitate displaying a menu with "hot keys". Like the
od_send_file() function, od_hotkey_menu() will display an
ASCII, ANSI or AVATAR file. However, od_hotkey_menu() also
allows you to pass a string listing possible hot keys. If
the user presses any of these keys while the menu is being
displayed, menu display will immediately cease, and the
function will return the key pressed by the user. (See
page 71)
- The od_send_file() (the ASCII/ANSI/AVATAR file display
routine) no longer sends the EOF character if it happens
to exist at the end of a file.
- In addition to the EZVote OpenDoors tutorial door, an
number of other example doors are now included in the
OpenDoors package.
- A few errors have been corrected in the documentation, and
additional information has been added about the new
features in this version.
VERSION 5.00 Version 5.00 represents several major steps forward for
OpenDoors. In addition to numerous bug fixes and minor
improvements, a number of major new features have been added to
this version. These include an optional multiple personality
system which allow the sysop to choose the status line and
function key style they prefer. This version also adds text-mode
support for RIP (Remote Imaging Protocol) graphics, and adds a
group of advanced ANSI/AVATAR/RIP functions for scrolling areas
of the screen, saving and restoring portions of the screen and
creating pop-up windows and menus. Also new in this version is
support for compilers other than Borland/Turbo C(++), such as
compilers from Microsoft. Version 5.00 also adds built-in
communications support, making the use of a FOSSIL driver
optional. Furthermore, direct support for additional BBS systems
has been added. The list below provides more detail of the
changes and new features in version 5.00:
- The nonstop key ([=]) now works correctly during
FILES.BBS listing.
- New door information file formats now supported include:
RA 2.00 EXITINFO.BBS.
- If the TASK environment variable is set, OpenDoors will
now use its value to determine the current node number.
- The od_control.od_spawn_freeze_time variable now works
correctly. Previously, the user's time would always be
frozen during od_spawn...() execution, regardless of the
value of this variable.
- A new feature known as the "Multiple Personality System"
has been added to this version. If you choose to include
the Multiple Personality System in a door, the sysop will
be able to specify which of a number of "personalities"
should be used. Each personality defines the statusline
appearance and function keys seen by the sysop, and has
no effect on the door's operation from the user's
standpoint. OpenDoors 5.00 includes personality
definitions for WildCat, RemoteAccess, PC-Board, and it's
own simplified RA style status lines. You can also define
your own personalities by writing a personality
definition function. If your choose not to include the
Multiple Personality System in a door, you will still be
able to define which single personality you wish
OpenDoors to use.
- This version of OpenDoors can be used with a larger
variety of compilers than where supported by the previous
version. OpenDoors 5.00 is known to work with all
versions of Turbo C, Turbo C++, Borland C++, Microsoft C,
Microsoft C++, Quick C and Visual C++. It should also
work with any other MS-DOS based ANSI C compiler that
supports the Microsoft/DOS .OBJect and .LIBrary file
formats.
- A new diagnostics feature has been added to OpenDoors,
which allows you to determine the reason for the most
recent OpenDoors function failure. When any OpenDoors
function returns a failure condition, it also sets the
new od_control.od_error variable to indicate the reason
for the failure.
- Added additional definitions to OPENDOOR.H, to map names
of OpenDoors functions and variables with the word
"colour" from the U.S. spelling "color". In other words,
both od_set_colour() and od_set_color() are now
recognized by OpenDoors.
- The od_list_files() now supports more intelligent path
specifications. If the parameter to od_list_files() is
NULL or empty, it will search for a FILES.BBS file in the
current directory. If a directory path is specified, it
will look for a FILES.BBS in that directory. If a full
directory and filename are specified, the specified
filename will be used in place of FILES.BBS.
- To save space, the compact memory model library is no
longer included in the normal OpenDoors package. The
compact memory model library is now available seperately.
- A new function, od_set_dtr(), has been added to allow the
DTR line to the modem to be manually controlled. This can
be useful in writing programs where you wish to force the
modem to hangup, such as a call-back verification door.
- Added additional support for various DOS multitasking
environments. OpenDoors is now specifically Microsoft
Windows aware. OpenDoors also now gives up time to other
waiting tasks when it is idle during chat mode.
- The od_edit_str() "M" mode now capitializes a character
following a dash '-' character.
- When transmitting more than one character at a time,
OpenDoors now uses the FOSSIL trasfer block function,
instead of multiple calls to the transfer character
function. This should help to improve performance over
high speed connections when running on slow PCs or under
multitasking environments.
- OpenDoors 4.10 would not correctly change the display
colour from high-intensity back to low-intensity. This
problem has been fixed.
- OpenDoors now recognizes DORINFO?.DEF filenames with
alphabetical identifiers (ie, DORINFOA.DEF thru
DORINFOZ.DEF) for nodes 10 thru 35.
- Improvements have been made to the logfile system. An
exit at errorlevel zero no longer causes garbage to be
written to the logfile. The logfile functions have been
made more reliable when operating under low stack
availability conditions. In the past, if a large number
of local variables where allocated on the stack, the
logfile functions would fail, often writing garbage to
the logfile. When the user pages the sysop for chat, the
user's reason for wishing a chat is also written to the
logfile.
- Support for text-mode RIP (Remote Imaging Protocol)
graphics has been added. Because this version of
OpenDoors always operates in DOS text-mode, none of the
graphics mode RIP features (such as drawing lines,
circles and displaying icons) will appear on the local
screen. Plans for a version of OpenDoors that will
operate in graphics mode and optionally display graphics
locally are currently under consideration. In this
version, RIP support includes a number of new features.
OpenDoors will now recognize the RIP setting passed in an
RA 2.00 EXITINFO.BBS file and WildCat DOOR.SYS file, and
also allows the RIP setting to be specified in a custom
door information file. The od_send_file() and
od_hotkey_menu() functions will now search for files with
.RIP, .AVT, .ANS and .ASC extensions. When displaying RIP
graphics to the remote user, a pop-up window appears on
the local screen, indicating to the sysop which file is
being displayed.
- A set of new functions have been added to permit advanced
screen manipulations. These functions include
od_gettext() and od_puttext() to save and restore
portions of the screen, and od_save_screen() and
od_restore_screen() to save and restore the entire
screen. od_scroll() can be used to scroll any portion of
the screen upwards or downwards. od_save_screen() and
od_restore_screen() will operate in any mode, but the
other functions require ANSI/AVATAR/RIP mode to be
available.
- Three additional functions, od_window_create(),
od_window_remove() and od_popup_menu(), have been added
to facilitate the creation of popup windows and menus.
When such a window or menu is removed from the screen,
the are of the screen "under" the window is returned to
it's original state. This allows you to create multiple
overlapping windows within a door program. The
od_popup_menu() function creates a popup window with a
menu from a simple menu definition string. The user can
select an option from this menu by pressing the key
associated with an option, or by moving a menu selection
bar using their arrow keys. These three functions require
an ANSI/AVATAR/RIP mode to be available.
- A new function, od_chat() has been added, to allow you to
explicitly invoke the OpenDoors chat mode from within
your program.
- A new setting variable, od_control.od_always_clear has
been added. When set to TRUE, od_clr_scr() will always
clear the screen, regardless of the user's screen
clearing setting. When set to FALE, od_clr_scr() will
only clear the screen if the user has screen clearing
enabled.
- It is now possible to configure the errorlevels OpenDoors
exits with under various circumstances, such as when the
user runs out of time remaining online. See the
od_control.od_errorlevel variable
- A new setting variable, od_control.od_force_local, can be
used to easily force OpenDoors to operate in local mode.
Using this variable you can easily add a command line
parameter such as "-local" to allow the sysop to force
your door to operate in local mode. When OpenDoors is
forced into local mode using this variable, it does not
look for a door information file, and uses default
settings for the user's name, etc.
- OPENDOOR.H now sets structure packing to single byte
alignment for the od_control structure when Borland and
Microsoft compilers are being used. In the past,
programmers using OpenDoors have experienced difficulties
the od_control structure when the compiler has been set
to use word packing.
- OpenDoors now closes the FOSSIL driver prior to
performing a spawn or sysop DOS shell. This allows doors
or other communications programs which use the FOSSIL
driver to be executed while the door's execution is
suspended.
- When used with a FOSSIL driver, OpenDoors normally
changes the BPS rate to that passed from the BBS (if the
BBS passes a valid FOSSIL BPS rate). This BPS rate
setting may now be disabled by setting the
DIS_BPS_SETTING bit of the od_control.od_disable
variable.
- A function hook has been added to allow you to install a
function to be called whenever od_kernel() executes
(od_control.od_ker_exec). Another function hook,
od_control.od_time_msg_func, can be installed to override
OpenDoor's time limit warning messages.
- A new array, od_control.od_hot_function, allows the you
to define functions to be called when any of the
programmer-defined sysop hotkeys have been pressed.
- A function hook, od_control.od_no_file_func, has been
added. This function will be called whenever OpenDoors is
unable to find or read a door information file. This
allows you to add your own door information file reader,
or to provide a local login prompt when no door
information file is present.
- Previously, OpenDoors would stop correctly updating the
user's remaining time at midnight when running under
certain BIOSes. This problem has been fixed.
- The current display colour attribute can now be accessed
through an control structure member,
od_control.od_cur_attrib.
- od_send_file() and od_hotkey_menu() no longer pause with
a "Continue?" prompt prematurely in files that have line
lengths greater than 254 characters.
- The local keyboard may now be disabled by setting the
DIS_LOCAL_INPUT bit of od_control.od_disable. This only
affects the sysop's input in circumstances that input is
also accepted from the remote user; this setting has no
effect on the sysop function keys.
A new function hook: -
void (*od_control.od_local_input)(int);
has been added. If set, this function will be called
whenever the sysop presses a non-sysop-function key on
the local keyboard.
- od_control.od_clear_on_exit now controls whether the
screen is cleared before shelling or executing
od_spawn...(), in addition to before OpenDoors shuts
down.
- od_page() now restores the original display colour before
returning.
- It is now possible to display an entire string of
characters with terminal emulation, using the new
function od_disp_emu().
- OpenDoors will now display a small popup window when
disconnecting the current connection.
- A new variable, od_control.od_in_buf_size, can now be set
prior to calling any OpenDoors function to set the size
of OpenDoors combined local/remote keyboard input buffer.
By default, this buffer is 256 bytes in size.
- Previously, there were a number of OpenDoors API
functions that would not correctly initialize OpenDoors
if they were the first function called in the program.
This has been fixed.
- To facilitate setting of bps rates up to 115,200,
od_control.baud is now an unsigned long.
- A new setting, od_control.od_no_ra_codes, has been added
to disable the use of RemoteAccess/QuickBBS control codes
by od_send_file()/od_hotkey_menu()/od_disp_emu(). The
RemoteAccess/QuickBBS ASCII 1 "pause for key" is also now
recognized.
