Serial Ports (COM12 ~ COM56)

AIMB-281 supports six serial ports. COM34. COM56 supports RS-232. COM12 sup-
ports RS-232/422/485 (supports RS-485 auto flow control). JSETCOM3 &
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.
