It's port 23, dude..
20 = FTP Data
21 = FTP Command
23 = Telnet
25 = SMTP (Mail)
I've only had luck using Telnet on its happy port 23. Ports 21 and 25 seem to
just hang up the other server. It's probably those negotiation codes, like you
said.
It does seem like there should be a generic something program that can
communicate over any port, because most of the commands and responses are text
anyway.. but it doesn't seem like there is one.
