Putting together a USB 16F877 rotator control A/D serial and LOGIC

Got a few options

Predict as the AZ/EL engine and perl scripts.

1. Completely autonomous - quite hard to do in a PIC
2. Use the A/D and just send data back to LINUX and get LINUX to turn relays on / off via parra port
3. Send AZ and EL to the PIC, do a ASCII to BIN and then get the PIC to drive the rotators.
4. Use the A/D and send data to LINUX and then send back a serial command on what to do.
