Hmm, if you don't see that, then it is not for you.
Basically you adapt the code for your purposes.
You assign values to variables
port
client_ip if you want a white list - otherwise remove that if-section
tty

then add a dbg proc like (or remove calls to dbg)
proc dbg {what } {
   puts $what
}

then you run it via tclsh (I think it is installed in raspbian else
sudo apt install tcl)

The filevent does the rest

But as others have pointed out - nc/netcat does the job as well
If you are not a programmer - then that is a better route.
If you needs are more special - then use something you can adapt
yourself - like above
