all characters not of interest for Telnet/RFC 2217.
The idea is that the reader thread pushes data from the socket through
this filter:
for byte in filter(socket.recv(1024)):
# do things like CR/LF conversion/whatever
# and write data to the serial port
serial.write(byte)
(socket error handling code left as exercise for the reader)
