Serial Port Interface
Serial port A and B(RS-232C Ports)
The PANECON-PC is equipped with two RS-232C-compliant serial
port connectors (SERIAL1: Serial port A and SERIAL2: Serial port
B). You can use BIOS Setup (described in Chapter 3) to configure
an I/O address, interrupt and unused state for each of the ports
independently. (The same I/O address and IRQ cannot be shared
with any other device.)
Table 5.4. SERIAL A and B I/O Addresses and Interrupts
COM I/O address Interrupt

2 2F8h - 2FFh
3 3E8h - 3EFh
4 2E8h - 2EFh
IRQ 3
IRQ 4
The BIOS defaults to the following factory settings:
Serial port A: COM1(3F8h-3FFh),IRQ4
Serial port B: COM2(2F8h-2FFh),IRQ3
