These are fundamental to the telnet protocol. The system is set up so that if either end of the connection cannot support a particular option, then it is disabled. Don't futz with this, or you will have an inoperable telnet service. Either end has to at least be able to tell the other that it won't support an option. And if it doesn't recognize the option, it still has to reply that it doesn't support it.
FWIW, I wrote (in C) a complete telnet (client and server) stack from the DDN White Book specs for a real-time operating system almost 20 years ago. I may be a bit rusty on the details, but I understand this issue completely.Sometimes, real fast is almost as good as real time.
