Re: [BLUG] The Hub raw chat over telnet/netcat

I read the page.

My understanding is that there are both block and line methods to
communicate via the Telnet protocol. Normal telnet sessions use
character mode, but MU*s and talkers normally use line-mode.

It looks like the hub was written with a character/block bias, and
you're trying to use it in a line-mode way.

What we're seeing is that it appears to be doing character-based
buffering of whole blocks with no regard to lines.
