I don't know what you modified, but the effect is now very positive!!!!! I made just a short test as it is totally cloudy, but the driver seems now to behave correctly, and communicate with the Pulsar with nearly no glitches.
Did you introduce delays?
I just found a small issue when slewing and at least once (over 3-4 attempts) the slew failed. I found in the log that nearly always the RES to the slew command is not valid at the first attempt. See below. Probably a small detail to tune.
Thank you so much for the good job and the support!
