&gt; &gt;[Bruce Mitchener:]
&gt; &gt;
&gt; &gt; &gt;To turn echo off: `[255, 251, 1, 0, 13]
&gt; &gt; &gt;To turn echo on:  `[255, 252, 1, 0, 13]
&gt; &gt;
&gt; &gt;I understand the first three bytes of these (IAC, WILL/WONT, ECHO), but
&gt; &gt;what are the NUL and the CR for? Do some telnet clients require those?
&gt; 
&gt; 
&gt; Woops.  The evils of blindly copying something.  I'll pass this along to the
&gt; people that work on ColdCore.
&gt; 
&gt; &gt;My testing (with a fairly small set of telnet clients) shows that
&gt; &gt;some do not respond to this correctly. They signal back that they
&gt; &gt;will start echoing again, but don't do so.
&gt; 
&gt; 
&gt; Can you tell me which clients had this issue?  I'd like to pass that along
&gt; also for test cases.
&gt; 
&gt; &gt;Note also that if you try to do any telnet commands like this, you should
&gt; &gt;be prepared to either pay attention to, or discard, the replies you
&gt; &gt;should get back. Typically [255, 253, 1] / [255, 254, 1].

Can I always assume that if I get a \377 (255 in decimal) then the next
two chars are also part of a telnet command (and so I may dis-regard
them?)

I'll try to look up the rfc tomorrow....

Thanks,
Ben
