It was my understanding that any option can be (re)negotiated at any time.  If
as a result of that negotiation the TN3270 session is no longer valid (WONT
BIN) the TN3270 session is terminated and the host notified.  That is how
McDATA currently tries to handle it.  It would be nice if this were prohibited
but that is perhaps not in keeping with the TELNET culture.

I certainly agree.
