OK, I finally took the plunge and started learning how to use sockets
yesterday.  I have a small program that chats amongst machines happily now,
but there is one catch: how do I read a single CHARACTER at a time from
a socket descriptor?  I wrote my own small server, and am using telnet as
my client, 'til I get TIME to write one.  Is telnet doing the buffering
on its end, or as there something I can do on the receiving end?  I tried
using some ioctl and fcntl calls that looked promising, but NOPE.  I have
yet to resort to setbuf or its cousins.  Is there some obvious solution,
or is it just telnet doing its wonderful magic again??  :|

Just another UNIX hacker....
