Thanks Bob
I'm using picaxe microcontrollers because they're very easy to use, and found one user trying to interface a dome control software using ascom with his picaxe.
else i might try and develop a driver that emulates the LX200 protocol because the functions that I need are just for slew, go to and tracking, nothing more. of course that will include position feedback.
this was the picaxe - ascom attempt.

i also found this PIC based project using ascom standards that looks interesting.
