Paul, here is the routine I wrote to do a partial telnet negotiation.
It's easy to expand if you need more sequences to be handled. You will
probably have to adjust the I/O routines to suit your environment. The
idea here is that telnet_get() is called to retrieve the next char in the
input stream. The routine locally responds to the far end as needed and
adsorbs the negotiation sequences. So telnet_get() sits between the "raw"
input from TCP/IP and the application.
