So I had a go at using SOCAT and although it's working it doesn't seem to like multiple connections on the TCP port. Although it will accept the connection it seems to output data from Serial>Ethernet is a round robin kind of way.
Reason I had two connections to it was to ensure the pipe was always read as the other post it was mentioned if the pipe isn't cleared there would be memory problems and I noticed not all the data was getting to all the TCP connections..
Anyway here is the code if you want to check it out.
Socat
sudo socat PTY,link=/dev/ttyS81,mode=666,group=dialout,raw TCP-LISTEN:40501,fork,reuseaddr &
sudo socat PTY,link=/dev/ttyS82,mode=666,group=dialout,raw TCP-LISTEN:40502,fork,reuseaddr &
