3.5.3 Serial Ports (COM1~COM3)
This motherboard supports three serial ports: COM1, COM2, and COM3. COM1 and
COM3 operate in RS-232 mode. COM2 offers one of three modes: RS-232/422/485;
the mode for COM2 can be set using JSETCOM2. These ports can connect to serial
devices, such as a mouse or a printer, or to a communications network.
The IRQ and address ranges for both types of 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
should happen to have problems with a serial device, be sure to check the pin
assignments for the connector.
