Caution
The COM2 port can be used (only one at a time) for the touchscreen
controller, IrDA interface, or RS-232 connector. The BIOS setup
determines whether COM2 is used for either the connector or the IrDA
interface. Jumpers on the touchscreen controller select the COM2 port or
the AUX port.
VGA Connector
The VGA connector is a 15-pin connector.
