Infrared Support
IrDA connector is five pins that support Hewlett Packard HSDL-1000 compatible
infrared (IR) transmitters and receivers. In the Setup program, Serial Port B (COM2) can be
directed to a connected IR device. (In this case, the serial Port B connector cannot be used.) The
IR connection can be used to transfer files to or from portable devices like laptops, PDAs, and
printers. The Infrared Data Association (IrDA) specification supports data transfers of 115
Kbit/sec at a distance of 1 meter.
