That sounds very wierd indeed, it *must* be one of severeal factors.
1) You have a problem with the seriel card.
2) setserial is setting up the devices incorrectly.
3) You have symbolic links in you /dev directory configured improperly.
With setserial you can check the I/O and IRQ of every seriel port.
setserial /dev/ttyS0 should show;
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
Which is a standard configured port.
In the /dev/ directory there would be a link to whatever device is used, ie
i have my seriel mouse on ttyS0.
ls -al /dev/mouse shows;
/dev/mouse -> ttyS0
I do not have a modem on ttyS1 however you should see a link for example;
ls -al /dev/modem should show;
/dev/modem -> ttyS1
Check also that the mouse is being started correctly, on my Slackware system
GPM is started with 'gpm -m /dev/mouse -tmsc' once again if you have a
misconfiguration in the /dev directory that could cause wierd things to
happen, i have NOT tryed to simulate your problem however to backup my
thoerys, however from all the information above you should be able to solve
the problem yourself.
It seems you "definatly have a IRQ conflicht".
