I'm having what appears to be a conflict between my mouse and modem.  In
fact, I assume it's an IRQ conflict.  Here's what happens:

If I run any comm or fax program in windows the mouse will freeze up and I
can't use the mouse again unless I run DOS prompt and exit.

If I run a comm program under DOS, then often the modem doesn't respond
until I click a mouse button or move the mouse.  Then I can type "at" and
get the "OK" response.

I'm guessing the problems stems from the fact that the mouse is on Com1 and
the modem is on com3 so they share the same IRQ.  I tried resetting the IRQ
for either port to 11,12, or 13 but it still didn't work properly. 

I'd really appreciate your help with this.

Scott
