I have been attempting to write a program in TURBO-C in graphics display
mode which uses my serial mouse. My mouse works fine with various commercial
software packages, and I have successfully written TURBO-C programs that
use the mouse in *text* display mode, so... I suspect the difficulty is related
to the fact that I have a Hercules card. I initialize graphics mode, set
location 0x0040:0x0049 to the value 6, then reset the mouse driver with a
call to int 0x33 function 0. I make the int 0x33 call to un-hide the mouse
cursor, it comes up just fine and everything, but when I try to return to
text mode and exit, the machine just hangs up. None of the references I have
indicate any special tricks are required here. Does anyone know what I
am doing wrong, or know of a really good programmer's reference for the
mouse???

 Thanks in advance!
