I now have a 10k pullup resistor fitted to the Rx line and using Minicom on the Pi I can see valid responses from the mount ....however,

Still no joy connecting using indi_eqmod_telescope (exactly the same) and indi_synscan_telescope. The latter spits out one Tx when the connect button in KStars is pressed. But it always says the following in the KStars window:

2019-03-28T15:38:12: [WARNING] Synscan Mount not responding
2019-03-28T15:38:12: [WARNING] Communication with /dev/ttyUSB0 @ 9600 failed. Starting Auto Search...
2019-03-28T15:38:12: [WARNING] Synscan Mount not responding

Using minicom on /dev/ttyUSB0 I get correct responses from the mount.

One last question. I do not have indi_synscanlegacy_telescope on my PiZero. How would I add that to the drivers?
