[CentOS] TCP port to TTY/Serial Port?

Hello,
  I'm trying to configure my system such that I have a TCP port listening which will send all data it receives to a serial port.

ie:   tcp/2112  -->  /dev/ttyS0

My goal would be to be able to:

Use netcat to create the listen and redirect to a serial port:
  $ nc -l 2112 > /dev/ttyS0

Then in another window, run minicom at /dev/ttyS0

Then in a 3rd window,
  $ telnet localhost 2112
 "Type things, hello world"

But, I can never get the text to show up in the minicom window.


I read different variations on the netcat command, including:

$ nc -l 2112 <> /dev/ttyS0
or
$ nc -l 2112 > /dev/ttyS0 < /dev/ttyS0


But none seem to do the trick.

Anyone have any ideas on what I'm missing here?

Any help would be great.

Thanks!
