Another possibility might be to put the modem on another IRQ if it's an internal modem. I did this with one system -- put the modem and parallel port on IRQ 7 (I would have used a higher IRQ, but the modem is an 8-bit ISA card, so it can only use the first 8 IRQs). Win NT didn't like it, but I mostly use OS/2 on that system, and OS/2 didn't care unless I used both the modem and printer at once.
The mouse driver likely grabed COM1 and wouldn't let anything else use it, so disconnecting the mouse to plug in anything else likely won't work. At least with OS/2, the mouse driver loads before the serial port driver, so the serial port driver never touches a serial port used by a mouse. Windows may do something similar.
