Hi Russell,
that was the trick to get communication between Communicator and Focuser running again.
But didn't help in my actual issue.
I can test and tune the motor with servoconfig, but can't write (and read the setting from the controller) the new settings to controller: "suspects a problem with the send", after that "no commun 1"
I have to select the same port again to get connection to Addr. 1 again.
Is there a special setting for the serial port?
Servus
