Ok I figured out what I didn't know that I needed to understand to make this work and I thought I'd share my findings with anyone else that might try to make a node-red telnet connection. I didn't use the telnet-client, I couldn't find any resources to understand how to use it. I didn't use TCP-IN or TCP-OUT nodes, I only used one TCP-Request node set to never close the connection. The biggest issue I had was when trying to replicate the commands I would type into a terminal to open the telnet connection I needed to use the carriage return and new line as a buffer and not a string. Instead of string = '\r\n' you need to send buffer = [80] for the telnet server to accept the return character.
