Dear all,
I am using C Programming language. I am currently using VT100 emulation on my HyperTerminal as a Telnet program.
Let's say I want to send certain commands to the HyperTerminal or Telnet for example, change you emulation from VT100 to TTY, etc...
Anyone has experience on this? Manipulating the Telnet environment with C Programming?

came across this just recently. It's a funny, easy to read introduction.
Hats off! Didn't verify that everything is 100% uptodate, but defo gives you enough insight to start you off for further research

from the server first send an IAC DO TERMINAL-TYPE
the client will respond with IAC WILL TERMINAL-TYPE if it supports terminal type negotiation.
negotiate with the client using this sequence as many times as needed.
server: IAC SB TERMINAL-TYPE SEND IAC SE
client: IAC SB TERMINAL-TYPE IS DEC-VT220 IAC SE (responds with one of the terminal type it supports.)
for details see RFC 1091 http://www.faqs.org/rfcs/rfc1091.html
if you are unfamiliar with the telnet protocol, you may want to first read these:
