I presume a Windows system.
Under the Control Panel you should find a tool for "Infrared"; open
it, pick the "Options" tab.
My laptop shows: enable infrared communication on /COM2/ (drop-down)
followed by: Providing application support on COM4 and LPT3
I believe this indicates that I would use COM4 in a program, the OS
takes the COM4 data and handles the conversion to Infrared protocol
with the IR port being a physical COM2 for interrupt purposes.
