Serial Ports (COM1~COM2)
AIMB-274 supports two serial ports, COM1 supports RS-232 function, COM2 sup-
ports RS-232/422/485 function by BIOS selection.
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.
