2.7 Serial Ports (COM1 & COM2)
The AIMB-764 offers two serial ports (one on the rear panel and one
onboard). JP1 is used to select the RS 232/422/485 mode for COM2.
These ports can connect to a serial mouse, printer or communications 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-232/422/485 standards in different
ways. If you are having problems with a serial device, be sure to check
the pin assignments for the connector.
