- PCanada BBS Graphics System 07/22/84
- ===========================
-
- General Overview
- ================
-
- The PCanada GFX Graphics Sub-System is quite easy to use. There
- are only two requirements in order for your system to receive FULL
- COLOR Graphics Screens. First, you must be using an IBM PC with a
- color graphics adapter and second, you must be using the GRAPHICS
- DRIVER files titled GFX.COM and GFX.LIB along with your COMMS software.
- Graphics Screens will appear on your system in less than 1 second at
- 1200 Baud and about 3.5 seconds at 300 BAUD.
-
- The two most current DRIVER FILES and their associated instructions
- (GFX.DOC) are available for DOWNLOAD from the PCanada Host Communications
- System at all times. They will operate with PC-TALK, CROSSTALK (certain
- versions) and ASCOM totally transparent to you. They will probably work
- with a multitude of other communications programs as well, however, we
- have only tested the above mentioned ones. Please advise us as to others
- that you may find that work equally as well so that we may add them to
- this list.
-
-
- How to use the GFX System
- =========================
-
- 1/ Ensure that the two files GFX.COM and GFX.LIB are resident on the
- default drive of your system when you load your current communications
- software.
-
- 2/ Then start your communications program as in the following examples:
- ENSURE that your COMMS protocol is 8 Bits, NO Parity, 1 Stop Bit.
-
- A> GFX [Name of your COMMS Program and Extension)
-
- NOTE: The extension (.EXE or .COM) must be explicitly typed)
-
- IMPORTANT: If you forget any of the instructions on how to start
- the GFX system, then simply type GFX and touch <ENTER> at
- your DOS prompt. ie: A>GFX [ENTER KEY]
- A help screen will appear with a full explanation of the
- command syntax required to use the system.
-
-
- EXAMPLES
- ========
- A> GFX PC-TALK.EXE
- or
- A> GFX ASCOM.COM
- or
- A> GFX XTALK.EXE [optional .XTK file]
-
- NOTE: When using XTALK (Crosstalk), after the program
- starts, type the command VERS to see what version
- of XTALK you are blessed with. If you have version
- 3.40 (11/18/83) or earlier then the GFX graphics
- system will work fine. However, if you have version
- 3.41A (03/01/84) or later, you're out of luck. The
- XTALK programmers decided, in their wisdom, to stop using
- standard INT 10 BIOS calls to print to the screen and
- instead wrote their own video driver. We guess that
- their programmers have never read the section of the
- DOS manual that talks about programming standards and
- the maintaining of compatibility. Oh well...the result
- is that those versions of XTALK with the HOME BREW
- video driver totally prevent the PCanada GFX system from
- operating at all. There may be versions of XTALK in
- between those two dates, but your guess is as good as
- ours to whether they work or not with the GFX system.
- Please let us know so that we may update the .DOC file
- for everybody. If your version of XTALK will work then
- you must also turn both the IN-FILTER and TIMER settings
- OFF or the GRAPHICS will not function correctly either.
-
- NOTE: When using PC-TALK.EXE in the auto-redial mode,
- if you are not present at the time of connection
- to hit a key to start viewing the HOST system,
- PCanada will indicate NO ECHO of the GFX graphics
- driver and turn the Graphics toggle OFF. The driver
- is still loaded and the only thing you'll miss is
- the sign-on screen. At the PCanada MAIN MENU, simply
- type <T> for TOGGLE that allows you to go into the
- appropriate section to turn the Graphics toggle back ON.
-
- 3/ As an option, the LIBRARY FILE for the particular BBS that you
- are signing on to (if not PCanada) may also be stated after you
- type GFX at the standard DOS prompt. The DRIVER program (GFX.COM)
- will default to the PCanada LIBRARY titled GFX.LIB in the absence of
- any other specifically declared LIBRARY name.
-
- For example, suppose another BBS starts using the GFX GRAPHICS
- SYSTEM. They would not be using the LIBRARY file titled GFX.LIB
- but instead may be assigned the LIBRARY file name of GFX01.LIB.
- If you were to dial up that BBS instead of PCanada, then you
- would type the following.
-
- EXAMPLES
- ========
- A> GFX GFX01.LIB PC-TALK.EXE
- or
- A> GFX GFX01.LIB ASCOM.COM
- or
- A> GFX GFX01.LIB XTALK.EXE [optional .XTK file]
-
- NOTE: When using XTALK (Crosstalk), after the program
- starts, type the command VERS to see what version
- of XTALK you are blessed with. If you have version
- 3.40 (11/18/83) or earlier then the GFX graphics
- system will work fine. However, if you have version
- 3.41A (03/01/84) or later, you're out of luck. The
- XTALK programmers decided, in their wisdom, to stop using
- standard INT 10 BIOS calls to print to the screen and
- instead wrote their own video driver. We guess that
- their programmers have never read the section of the
- DOS manual that talks about programming standards and
- the maintaining of compatibility. Oh well...the result
- is that those versions of XTALK with the HOME BREW
- video driver totally prevent the PCanada GFX system from
- operating at all. There may be versions of XTALK in
- between those two dates, but your guess is as good as
- ours to whether they work or not with the GFX system.
- Please let us know so that we may update the .DOC file
- for everybody. If your version of XTALK will work then
- you must also turn both the IN-FILTER and TIMER settings
- OFF or the GRAPHICS will not function correctly either.
-
- NOTE: When using PC-TALK.EXE in the auto-redial mode,
- if you are not present at the time of connection
- to hit a key to start viewing the HOST system,
- PCanada will indicate NO ECHO of the GFX graphics
- driver and turn the Graphics toggle OFF. The driver
- is still loaded and the only thing you'll miss is
- the sign-on screen. At the PCanada MAIN MENU, simply
- type <T> for TOGGLE that allows you to go into the
- appropriate section to turn the Graphics toggle back ON.
-
- That's all there is to it. You then simple dial up PCanada (or any
- IBMPC BBS system that adopts the GFX GRAPHICS SYSTEM ) as you normally
- would and enjoy FULL COLOR GRAPHICS.
-
-
- Updates
- =======
-
- From time to time, we will be UPDATING both the DRIVER program,
- (GFX.COM) as well as the PCanada LIBRARY FILE (GFX.LIB). Don't worry,
- the PCanada HOST system automatically validates your current version
- number of both programs each time you sign-on and advises you when
- you must DOWNLOAD them again to keep up with our ever expanding GRAPHICS
- SYSTEM.
-
-
- Note for other SYSOPS
- =====================
-
- If you are interested in implementing the GFX GRAPHICS SYSTEM on
- your own BBS systems, then send us a note outlining your present BBS
- and include your mailing address so that we may send you full information.
- ALL enquiries should be addressed to PCanada care of Mr. M.A.E. LINDEN.
