I have an Orion RX2800PX azimuth rotor controller connected to COM3
(on a PCIe card, not USB) and use Hyperterminal to control it for remote
station operation.
The info provided below by Codrut is exactly what I see and do. I
actually have both azimuth and elevation rotors and use cammonds of the
form A90 to control the azimuth and E30 to control the elevation.
