The EOM is only for parsing feedback, it does not apply itself to
outgoing commands. Please see our wiki for documentation in this area.

I would try Fiasco's suggestion of adding a line feed and carriage
return to the end of the commands (these are added by default in
telnet when you press enter to send the command). You might even only
need a carriage return, depending on the protocol.
Heartbeats are only required if the system you are controlling
requires a heartbeat message to keep a connection alive. Most systems
do not need this. But you can also use the heartbeat Tx as a way to
poll the system for data by sending it a command every 3 seconds.
