Well, you give the answer already:
If the Control System does not respond to the Telnet session options negotiations, the session will not go ahead. As such, the control system will have to be programmed to negotiate the Telnet options with Tesira’s Telnet server.
So the only solution to do it in V-Control is to implement it. Thats why I point you to the ImagePro Network driver, because there you can see an aproach how to do this.
