The only IrCOMM I know of is part of the IrDA standard.  It provides
something that looks just like a typical serial port to the application,
but underneath is layered on top of IrLAP (packet based link level
prototocol for IrDA).  This means that a single byte at the COMM level
turns into a more complicated packet at the physical level.
Furthermore, the physical signalling used by IrDA is different from
Mindstorms.
