Subject: IO.getc (Based off of #45 MUD)

I have some questions about sockets, IO.getc(), and IO.ready?().


So my telnet server accepts  
connections.                                             That works.
It displays the  
prompt.                                                                  
               That works.
It accepts the single characters (IO.getc) without pressing return.    
That works.
But wait! Whenever I connect to the server (telnet localhost), there  
is always this string of characters that are:

??%??&??&??^C?????? ??!??"??'????

Where are those characters coming from, and is there a suitable  
workaround? I tried instituting a sleep 1 to allow the characters to  
pass (assuming it was a short stream), but they still came. I also  
noticed that this only happens when I press enter (which for me shows  
up a ^M. bwah?).

CODE:
       loop do
         character = sock.getc
         if sock.ready?
#          puts sock.ready?
#          puts sock
           case character
           when ?\C-c
             print "^C"
#            break
           when ?\r, ?\n, ?\C-M
             $writer[$output_buffer]
             show_prompt
           else
             $output_buffer << character
             print character.chr
           end
         end

I had to comment out 'break' so that I wouldn't get disconnected  
during the initial character stream.

What's going on?

Thanks,
