Serial Line: Communication problems when sending and reading single bytes
While @mauro worked on #663 (closed) he reported a bug in the ser2net interface in bliss. For the NHQ requests and response have to be send and received byte-by-byte. The current implementation of the serial line has a problem with that.
Related to this issue @sebastien.petitdemange pointed to the _rx_filter
and the IAC
is one of the bytes send by the NHQ.
