This plugin allows you to connect to an open shell on a TCP port using TMTerminal.

If you are using Linux, you can use socat to open a local shell on a port like this:

socat TCP-LISTEN:5000,bind=127.0.0.1,reuseaddr,fork EXEC:'/bin/bash -li',pty,stderr

This will open /bin/bash in an interactive login shell on port 5000 and restrict connections to localhost.
