   HTTP 1.x doesn't "suppot Telnet" either. Since Telnet is *mostly* just text   
   over TCP, some people use telnet clients to send/receive plain-text messages   
   (requests, commands, whatever) to/from servers that use plain-text TCP   
   protocols (e.g. HTTP, SMTP, FTP, NNTP, POP, IMAP, IRC, etc.) for testing   
   purposes. It's actually better to *not* use a Telnet client for this purpose   
   but rather a simple TCP client app, like netcat or perhaps the "raw TCP" or   
   "raw socket" feature of a terminal program. That way the client won't send or   
   expect Telnet commands (beginning with the IAC, 0xff character) that the server   
   isn't going to recognize or send.

   Most telnet clients can be used to debug HTTP (and other TCP) servers, but they   
   are not ideal for use.

   Yes.

   No.

   No, no implications for BBSes (that use Telnet).
