Most applications that use COM ports understand interrupt sharing and are capable of filtering out extraneous interrupts at the same level from a different device. The mouse driver should also be capable of ignoring stuff from the COM port. So choosing 3 or 4 will probably work. If that doesn't work I'd suggest 5. On my system at home my V-RAM VGA wouldn't work with the mouse on interrupt 2; perhaps display hardware is more finicky about interrupts than disk controllers are...
