Hi,

we are using a Planewave EFA focuser, with the current INDI version 1.9.3 on a Debian 11 system. Unfortunately, no connection is established, at least not a bidirectional one.

The focuser can be addressed correctly under Windows with the PWI3 software, so we can rule out a hardware problem due to the many adapters. 

Under INDI, however, the version of the focuser and the temperatures are displayed correctly. In contrast, the transmission of commands fails, with the following error messages:
[ERROR] Send/Receive mismatch and timeout
[ERROR] Serial I/O error: Timeout error.

I have attached the corresponding log file. Unfortunately, we lack an approach to identify the cause of the error and would be very pleased to receive any hints!

Many thanks and best regards
Simon
