Chapter 2 Connecting Peripherals
2.7 Serial Ports (COM1, COM2, COM3 & COM4)
The AIMB-766 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.
