- If you have an extended keyboard and your BIOS supports extended
- keyboards, a flag is set in the BIOS data area indicating your hardware
- configuration. PROCOMM PLUS (except version 1.0) looks at this flag and
- if the BIOS indicates an extended keyboard, calls the extended keyboard
- subfunction of INT 16 rather than the regular keyboard function to get
- keys from the BIOS keyboard buffer. Some TSR programs (such as Turbo
- Lightning) or mouse drivers do not support the extended-keyboard and
- therefore will not function under PROCOMM PLUS.
-
- A workaround for this problem is to make PROCOMM PLUS think you
- have a regular keyboard rather than an extended one by changing a single
- bit in the BIOS data area. This is exactly what REGULAR.COM does. Once
- you run REGULAR.COM (by typing REGULAR at the DOS prompt before going
- into PROCOMM PLUS) you will not be able to use your F11 and F12 keys,
- but you will probably be able to use your TSR or mouse driver unless it
- conflicts in some other way. After leaving PROCOMM PLUS you can run
- EXTENDED.COM to enable your extended keyboard functions again. Perhaps
- the best way to use these programs is in a batch file, e.g.:
-
- REGULAR
- PCPLUS
- EXTENDED
-
-
- NOTE:
- After forcing PROCOMM PLUS to think you have regular keyboard, there
- is no way to distinguish the extended keyboard's special keys. This
- means, for example, that the grey keys will act the same as their
- regular keyboard counterparts and that F11 & F12 will be unavailable.
