There are two approaches that brain-dead clients (MUD clients which don't
implement any telnet functionality but have realised that ignoring IAC
sequences sometimes locks your client solid and pisses off the user)
usually take to telnet commands. The first, and proper, way is to respond
"DONT" to any request. The second (dangerous) way is to respond "DO" to any
request. This is generally a result of not reading the standard very
closely. I'd suggest that, whatever clients you find which use the latter
method, you contact the developer if possible. On one occasion (MUSHclient)
a client author did this with nothing worse than a typo and was very happy
to have someone tell him what happened and how to fix it. Many/most client
authors actually WANT their products to work. ;)
