I am able to connect to ttyS0 with minicom 112500 8N1 and get a login prompt.
But when I telnet to ttyS0 via configured port 2000 I see a connection in ser2net but there is no data on the telnet console.
What am I doing wrong?
root@PC3:~# ps auxww | grep ser2net | grep -v grep
root 32479 0.0 0.0 1908 548 ? S 15:46 0:00 /usr/sbin/ser2net -p 9999 -c /etc/ser2net.conf -P /var/run ser2net.pid -u

Here is the telnet connection
$ telnet 10.16.1.13 2000
Connected to 10.16.1.13.
Escape character is '^]'.
tcpdump shows the initial connection to port 2000 but after there is no data going back to the other pc.
Typing and hitting enter in telnet does not send any data across.
