INTEGRATED COMMS
Parallel Port
Sets the parallel port as
LPT1 or LPT2 or disabled
Parallel 1 (378h, IRQ7) /
Parallel 2 (278h, IRQ5) /
Disabled
Parallel Port Mode
Sets the parallel port into
Centronics, ECP or EPP
mode
Centronics(R) /
Bi-directional EPP /
Bi-directional ECP
(DMA1 / DMA3)
If the peripheral has an ECP/EPP
interface, use a compatible cable.
Serial Port A
Sets serial port A to
COM1, COM2, COM3,
COM4 or disabled
Serial 1 (3F8h, IRQ4) /
Serial 2 (2F8h, IRQ3) /
Serial 3 (3E8h, IRQ4) /
