COM1 & COM2 ports can function as RS232/422/485 port. In normal settings
COM1/COM2 functions as RS232 port. With compatible COM cable they can function
as RS422 or RS 485 port. User also needs to go to BIOS to set ‘Transmission Mode
Select’ for COM1/COM2 (refer to Page 26) at first, before using specialized cable to
connect different pins of this port.
