Install ser2net

• Install

sudo apt-get -y libyaml-dev libgensio-dev
sudo apt-get -y install ser2net

• configure file test.yaml

#%YAML 1.2  # Use YAML version 2

define: &banner \r\nser2net port \p device \d [\B] (Debian GNU/Linux)\r\n\r\n

connection: &conn0
  accepter: telnet(rfc2217),tcp,4001
  enable: on
  options:
    max-connections: 4
    banner: *banner
    kickolduser: true
    telnet-brk-on-sync: true
  connector: serialdev,/dev/ttyUSB0,115200n81,local

Replace ttyUSB0 by your Serial port

• On the Beaglebone side

ser2net -l -n -c ./test.yaml

• On client side

nc 10.66.77.28 4001

where 10.66.77.28 is the IP or domain of BB Note that: nc require enter to flush the msg through tcp. You should enter after input sothat the msg can be sent

Configure file /etc/ser2net.yaml to run as the service

• cp test.yaml above to /etc/ser2net.yaml
• Note that the default service(/lib/systemd/system/ser2net.service) one don't have the constraint to start after network service. So need modify it before run
