Say Y here if you want to build support for the Parallax Litelink
dongle. To compile it as a module, choose M here. The Parallax
dongle attaches to the normal 9-pin serial port connector, and can
currently only be used by IrTTY. To activate support for Parallax
dongles you will have to start irattach like this:
"irattach -d litelink".
