I removed all MessageRequester() calls.
But still I get the following messages on the console:
IO maybe because I use OpenSerialPort() inside of the thread?[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-thread client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
Programname: ../../src/xcb_io.c:273: poll_for_event: Zusicherung >>!xcb_xlib_threads_sequence_lost<< nicht erfüllt.
