Install any serial prog like picocom

git clone https://github.com/npat-efault/picocom; cd picocom && make

Optional: Manually install in path as above makefile does not have an install rule

Edit sshd_config as follows:

• make sure port 22 is uncommented & add your new custom port

  Port 22
  Port 3001
  

• Now force a command this port

  Match LocalPort 3001
    ForceCommand /bin/picocom -b115200 /dev/ttyS8
  

Kermit example with killing existing port user (if any)

create a connection script, not sure if there is a proper place for it, I dropped ine in /etc/kermit/S0.ini

run bash -c '[[ $(lsof -t /dev/ttyS0) =~ .* ]] && kill -9 ${BASH_REMATCH[0]}'
set line  /dev/ttyS0
set baud 115200
set handshake none
set carrier-watch off
set flow-control none
connect
exit

and the sshd_config to match

Match LocalPort 3001
  ForceCommand /usr/bin/kermit /etc/kermit/S0.ini
