Hi Joe: Does he set up the modem with isapnp to place it on irq=5? If the modem is normally pnp then it could be placed anywhere. I think the object is to nail down where he wants the modem to live from a port/irq perspective. He would get a hang or at least have problems if the modem was left on the traditional irq=4 because that shares irq with com1/ttyS0. He can see where the modem is getting put in linux by looking at /proc/interrupts or /proc/ioports for the command ports.
