Thanks Melanie. I'm trying to find a means to avoid the use of a keyboard encoder to receive keyboard commands. For example, if I purchased an RF receiver module that plugs into a USB port of a PC, do I have to develop an application that runs on the PC that would accept serial data and convert it into keyboard commands?

I came accross this page that lists USB 16 bit keyboard positions at
http://www.win.tue.nl/~aeb/linux/kbd/scancodes-13.html.

Does this imply that a USB port can be used to receive keyboard commands directly without running a special application? Any advice would be appreciated.
