I am looking for a simple tool that I can use to control how TCP data
is split up among segments. I can't seem to figure out how to coax
Netcat into doing this.

Type: U S E R <space> ^D

The ^D causes netcat's read(2) to return the characters it already has.

You might also try stty -icanon for character-by-character reading in
netcat.

That's strange. Now netcat is doing that for me. I could have sworn
when I tried that before that I would get a little,

  E
   O
    F

Symbol on my terminal and netcat actually sent the \004
character. Maybe my terminal settings were mucking with things.

Thanks for making me look again. I should have known netcat could do
what I want.
