Netcat Serial
Sometimes there is a need to echo a serial port over the network for debugging here is a couple ncat tricks
On the Server
stty -F /dev/ttyUSB0 115200
cat /dev/ttyUSB0 | ncat --broker -l 127.0.0.1 1234 -k
You can change port 1234 to whatever makes sense.
On the Client
nc 127.0.0.1 1234
(client note: change 127.0.0.1 to the server IP)
