Say Y here if you want to build support for the ACTiSYS IR-200L
dongle. To compile it as a module, choose M here. The ACTiSYS
IR-200L dongle attaches to the normal 9-pin serial port connector,
and can currently only be used by IrTTY. To activate support for
ACTiSYS IR-200L dongles you will have to start irattach like this:
"irattach -d act200l".
