tested focuser control in BYE

Tested the RASC TC CAO GBO Optec TCF-S focuser with Backyard EOS and its ASCOM interface (via my hacked cable). It worked! With a USB-serial adapter based on the Prolific chip!

I was able to read/see the current focuser position and temperature data. I was able to move/nudge the focuser from within BYE. Sweet.

I didn't see an AUTO mode switch or button. But it looks like I can run out to the focuser and switch the hand paddle to an automatic mode and forget about it.
