Hi Tas,
I use the MCE controller file from here
[Link: remotecentral.com]The software requires a small app running on your PC to open up a TCP/IP port on your PC, and your Pronto sends commands direct.
I'm fairly sure you can send any alphanumeric key as listed here
[Link: kindel.com]The new Key: command seems to say that anything key can be sent, as opposed to MCE remote control commands.
It's quick and dirty!
Cheers, Lee
