Modem Use IRQ
This determines the IRQ which the MODEM can use for Power Saving pur-

Before you can use the Ring-in signal to wakeup your PC system, you have to
install the “External” modem to your PC system and tell the PC system which
serial port connects to the modem by selecting the IRQ in this field. (Officially
COM1 uses IRQ4)

failure occurred, the system will power-on when the power returns.
