Based on the symptoms you describe, this is almost certainly a problem with interrupts. Something else is using the interrupt your modem is using, or your modem is set to use the wrong interrupt for the port is uses. Cat /proc/interrupts and see what your various ports are using, or use setserial as I did below. I had to redefine the interrupt my modem used (via jumpers) to get it operational on COM3 (ttyS2). By default ttyS0 and ttyS2 share IRQ 4, and S1 and S3 share IRQ 3. This doesn't work under Linux, though (and not very well under DOS/Win). I don't use S3, so I have... $ setserial /dev/ttyS1 /dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3 $ setserial /dev/ttyS0 /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 $ setserial /dev/ttyS2 /dev/ttyS2, UART: 16550A, Port: 0x03e8, IRQ: 5 So, I have two working serial ports and a modem.
