capsmap - DOS TSR for remapping caps lock

-----------------------------------------

Author: John Tsiombikas   

This program is placed in the public domain. Do whatever you like with it.

Capsmap is a DOS Terminate and Stay Resident program, for remapping caps lock

to any other key. It does this by taking control of the keyboard interrupt, and

either modifying the BIOS keyboard flag bytes (for modifier keys), or appending

scancodes to the BIOS keyboard buffer, when it detects a caps lock

press/release. This remapping trick will work for most DOS programs which use

either BIOS or DOS calls to get keyboard input. It will not work however for any

programs which access the keyboard directly, like most games.

Two pre-built versions of the caps mapper are provided in the release archive.

 - `capsmap.com` maps caps lock to the left control key.

 - `capsesc.com` maps caps lock to the escape key.

If you wish to map caps lock to something else, you need to rebuild the program

after changing a couple of definitions in the top of `capsmap.asm`, following

the instructions in the comments. To figure out which scancode number to set in

the code, use the accompanying `testkeys.com` program.
