Ok if that's true then my basic assumption is wrong, but I think you may 
be wrong about the user's client not sending one character at a time.  
The telnet I use (linux stock telnet command) does send one character at 
a time.  If this weren't the case, I wouldn't be able to use pine, or any 
other hotkey-driven program, over a telnet connection.

So, if the client supports character transfers, it must be the server 
that doesn't, and since pine, lynx, and various other servers support 
character transfers, it should be possible to do the same with circle, 
although depending on how it works, you may miss some characters when 
polling other sockets.

I'd say it's possible, but not necessarily worth the trouble.  If you 
get it working I know there are lots of circle imps who would love to see 
it done.
