Want to use Mikrotik to communicate with your serial devices? No problem! Mikrotik supports RFC2217. Here is how you set it up:
Turn off the serial console:
/system console disable 0
Setup serial port:
/port setserial0 baud-rate=57600data-bits=8parity=none stop-bits=1
or
/port setserial0 baud-rate=auto
Test the connection between Mikrotik and the serial device:
/system serial-terminal serial0
Forward all traffic from single port (eg. 10000) to serial port (eg. serial0)
/port remote-access add port=serial0 protocol=rfc2217 tcp-port=10000
