Documentation for JOYREAD.ASM/COM
JOYREAD was written to allow me to adjust the potentiometers on my
joystick (the planes in Flight Simulator kept banking left on me !). It
continously reads and displays the values of the potentiometers which
sense the stick position and the status of the buttons. The program was
originally written for an XT clone using a software loop which directly
accessed the game adaptor port, however when I upgraded to an AT clone
with a higher clock speed this method was no longer adequate.
Fortunately, the new BIOS for AT machines contains a function which
solved the problem. The current version of JOYREAD allows one to select
either method to read the potentiometer values, pressing `m' toggles
between them.
