Running either example gives:

Yes, LCDd is running.

Hello,

"/usr/local/lib/python3.8/dist-packages/pylcddc/iothread.py"

Could you elaborate more on what type of operating system you are using? I gave the simple example a try against LCDd 0.5.9 with the curses driver and everything seems to be working fine.

Also, the exception that led to the thread's termination should have been assigned to c._iothread._thread_death_exception. Could you peek into that and tell us what it contains?

If you are not using a Linux distribution, I suspect the cause of the error is the SOCK_SEQPACKET socket type not being available on the platform that you have. As far as I know, that is Linux-specific unless additional software is installed.

If you confirm that, I could look into ways to replace the dependency on SOCK_SEQPACKET semantics - I wasn't expecting anyone to use this on anything but Linux platforms.

Thanks.
