Changing Printer Modes
Set the Parallel Mode option according to the type of printer or device connected to the parallel connector. To determine the
correct mode to use, see the documentation that came with the device.
Setting Parallel Mode to Disabled disables the parallel port and the port's LPT address, freeing its interrupt for another
device to use.
Changing COM Ports
Serial Port allows you to map the serial port COM address or disable the serial port and its address, freeing its interrupt for
another device to use.
