I mentioned in a thread about the Quantum Filter Wheel developed by Kaczorek (which works really well - thank you!) that I am using a Lakeside focuser...

I still have not had a response from the supplier, which is quite strange as they have been really helpful in the past...

I have run a few debug sessions via ASCOM, which has a Lakeside driver & have managed to pull out most of the command set...

All responses seem to be 7 bytes (6 characters + a hash) - the hash seems to be space padded to the 7th byte.
The only exceptions seems to be ??# -> OK# and the CI/CO move in/out responses (Started & DONE#)

Is this enough information for a focus driver?

There is no command to move to a specific step? e.g. 3445?

If I recall from the session I was running (I was using Focusmax with the Lakeside driver set to debug mode), when I issued a goto step number, it worked out where it was & the number of steps in/out needed, then send a #CInn or #COnn command for the nn of steps to move by.....

I will double check tonight or tomorrow, if I get a few minutes...

Ok you can easily customize one of the existing drivers (e.g. moonlite) to develop a driver for Lakeside focuser.

I would go for recording a session with wireshark so to grab all usb traffic. This way you can get proper signalling and carriage return/line feeds. That's how I started with developing Quantum Filter Wheel driver. Otherwise it might be a pain in the ass to go further with developing a driver for this focuser without access to the hardware.
