This is all in the telnet RFCs. In this case, you are looking for
<A HREF="http://www.pmg.lcs.mit.edu/cgi-bin/rfc/view?857">http://www.pmg.lcs.mit.edu/cgi-bin/rfc/view?857</A>
A search for 'telnet' and 'IAC' in the RFCs will yield a number of
documents that may be of interest:
<A HREF="http://www.pmg.lcs.mit.edu/cgi-bin/rfc/find?pattern=telnet+IAC">http://www.pmg.lcs.mit.edu/cgi-bin/rfc/find?pattern=telnet+IAC</A>
We do echo on/off control in Cold by writing a buffer to the connection.
To turn echo off: `[255, 251, 1, 0, 13]
To turn echo on: `[255, 252, 1, 0, 13]
Where these buffers are arrays of unsigned 8 bit values for characters.
The process of building a state machine for handling telnet IAC sequences
is covered in at least one of the books on networking mentioned so often
on here. The copies I use are at work, so I can't look to see which one
it is that has the information right now.
Hope this makes sense,
- Bruce
