Is it possible that you have a conflict between your modem and something
else, such as a mouse, or an ethernet card etc.?  This might cause the 
behavior you describe. Also, have you tried setting the protection level
higher on both the comm program (presumably window 1) and the other window?
Perhaps this would generate an exception indicating that one program
is using something that it shouldn't. I don't know if protected mode
covers the serial ports.

As an aside, you should be running the mouse on com1 and the modem on com2
since com2 is on interrupt 3 and com1 is on interrupt 4, thus giving the
modem higher priority than the mouse.
