PstRotator only turns right

[dg5cst]

Hello, I configured my rotator with latest code and can use them with serial commands. When connecting to PSTrotator via ethernet it only turns right not left.
I than fund an older code from 2019 on my pc and tried exact the same config.. This code worked perfect with pstrotator.
No glue?! Used GS232 both times.. The Easycom did not work at all with the newest code..
I would like to try a version from maybe 2021? Where can one found that?
I also do not See decimal places.. I activated the feature _one decimal place.. Aren't they transfered via gs232?
Many tnx Seb
