Option Negotiation
During TN3270e server option negotiation with TN3270e clients, the following rules
apply:

The BINARY and EOR options are implied.

During option negotiation, the client may send a WON’T TN3270E response. The
TN3270e server then negotiates traditional TN3270.

Terminals negotiate a null functions list; this is referred to as Basic TN3270E.
Printers support the following two functions: DATA-STREAM-CTL and
RESPONSES.
For details on Telnet option negotiation, refer to RFC 854 and RFC 855. For
information on RFC 854 and RFC 855, see Optional Manuals on page ix.
