I had a look at this. The function telnetConsoleParameters doesn't seem to exist (I could only find a reference for it in an old ebook) but there is a function called
telnetSetParameters.
telnetSetParameters( port, consolePass, listenPass [ , remoteEcho ] )
Purpose
Use the telnetSetParameters function to setup and accept telnet requests on a specific port.
Syntax
port – A numeric port ID.
consolePass – Password for read/write access to the console.
listenPass – Password for read access to the console.
remoteEcho – A boolean value to enable echoing to the client, false by default.
Returns
No return value.
I used centerPrintAll to send some messages about impending automated updates and restarts.
Is there a command that returns the playercount or a list of players connected to the server?
Telnet works, but man is it messy. It's a shame Torque 3D doesn't have an
RCON implementation, unlike UE4.
