... and 5250 (RFC2877).

Note that there was a draft-murphy-iser-telnet-02.txt attempt at 
RFC2877bis as recent as May 2004, which still uses EOR.

RFC1576 (which is cited in the PS document RFC2355 as "traditional 
TN3270") says:

    Currently, support for 3270 terminal emulation over Telnet is
    accomplished by the de facto standard of negotiating three separate
    Telnet Options - Terminal-Type [2], Binary Transmission [3], and End
    of Record [4].  This negotiation and the resulting data flow will be
    described below.

    [4] Postel, J., "Telnet End of Record Option", RFC 885,
        USC/Information Sciences Institute, December 1983.

It's probably necessary to do a full dependency analysis to do this 
right.

OMG, what a visit to the technology attic.
