I've been playing with Ubuntu for the first time past few days -- a real blast.

It occured to me this morning that it would seem quite possible to actually control a Linux PC with the incredible variety of terminal commands it has available?

You can actually control the processes of applications it looks like -- not just "run" them.

Am I thinking right here?

If you can have the Linux terminal program always open in the background, then you could somehow interface your commands (rs232?) to the PC you like and presto?

Possible?
