Page 91: Enabling the ir port

default for
Parallel Mode is ECP.
To determine the correct mode to use, see the documentation that came with the device.
NOTE: The ECP setting also works for most software written for the AT and PS/2 modes. Devices that
use ECP mode may come with special drivers that need to be installed in order to use these modes.
Setting
Parallel Mode to Disabled disables the parallel port and its assigned LPT address, freeing its
interrupt for another device to use.
For a change in the
Parallel Mode option to take effect, you must reboot your computer.
Changing COM Ports
Serial Port allows you to map the address of the serial port to COM1 (the default), COM2, COM3,
COM4, or to disable the serial port and its assigned COM address, freeing that interrupt for another device
to use.
Enabling the IR Port

1. Set the
Infrared Data Port option to COM1, COM2, COM3 (recommended), or COM4. The
default for
Infrared Data Port is Disabled.
2. Set the
Infrared Mode option to either Fast IR or Slow IR.
For a change in the
Infrared Data Port option to take effect, you must reboot your computer.
