Elizabeth,

I had many problems when I had my modem on COM2 and mouse on COM1.  Then
I swithced them (and reconfigured them properly) so the modem is on COM1
and the mouse is on COM2.  This miraculously solved my problems.  It is
worth trying.

Good luck,

Sounds like your modem may be on the same I/O or IRQ as your COM1.  I'm 
sure you checked it, but check again. Win95 doesn't do a very good job 
with legacy stuff.  Also, make sure that you have added the com2 port in 
the ControlPanel Port applet.  I was able to get stuff to sort of work 
with real mode stuff in the config.sys, but it really worked a lot 
better when everything was properly installed.  There is also a modem 
install wizard to run.

You might have to manually configure the modem to get Win95 not to hang 
the other serial port.

There are also settings for the modem init strings that you may have to 
tinker with

Good luck.

I've been troubled with the same combination of video, 486 and modem/serial
port. The problem is that the Diamond stealth card uses some internal
registers that have addresses that have the same last bits as the base
address of serial port com2. The problem is that the Diamond stealth driver
software writes information into registers of the UART of the 
modem/serial port which then acts funny.
My solution was to strap my ISA serial card/modem as com1 and use
the built in VESA combo card com2 for the mouse.

Does your COM2: use COM4:'s IO port address?  AFAIK the SVGA clash
issue involves COM4:'s IO address, although as COM4: shares IRQ3 with
COM2:, you may get some spill-over...

Me2; the beauty of mouse on COM2: is that you can add an internal
modem on COM3:, or an external on COM1:, and not have to worry about
IRQ clashes with the mouse, IO port clashes with S3 or misbehaviour
due to a "missing" COM3:    ;-)

I just flashed the bios on a Micron P 90 today and on reboot it said
there was a comport conflict....s3 card and modem, having been through
this before with s3 cards I disabled com port 2 and all is ok.
