**
** The main purpose is to read each OT Msg (9 bytes), or anything that comes
** from the OTGW hardware firmware. Default it assumes raw OT messages, however
** it can handle the other messages to, like PS=1/PS=0 etc.
**
** Also, this code bit implements the serial 2 network (port 25238). The serial port
** is forwarded to port 25238, and visavera. So you can use it with OTmonitor (the
** original OpenTherm program that comes with the hardware). The serial port and
** ser2net port 25238 are both "line read" into the read buffer (coming from OTGW
** thru serial) and write buffer (coming from 25238 going to serial).
**
** The write buffer (incoming from port 25238) is also line printed to the Debug (port 23).
** The read line buffer is per line parsed by the proces OT parser code (processOTGW (buf, len)).
