Serial Ports (COM1~COM2)

AIMB-231 supports two serial ports, and COM1 supports RS232/485/422 function
and 5V/12V selected by jumpers RS-485 without H/W auto flow control function.
These ports can connect to serial devices, such as a mouse or a printer, or to a com-
munications network.
The IRQ and address ranges for both ports are fixed. However, if you want to disable
the port or change these parameters later, you can do this in the system BIOS setup.
Different devices implement the RS-232 standards in different ways. If you have
problems with a serial device, be sure to check the pin assignments for the connec-
tor.
