TN3270 is a special subset of Telnet, that sends and receives data in
EBCDIC block-mode, with 3270 control sequences embedded. Non-EBCDIC
machines effectively need a 3270 emulator between the network connection
and the local display. Greg Minshall did a 'tn3270' for Unix which does
this function. 'tn3270's are also available for DOS PCs, from us and
IBM, and most IBM mainframe TCP/IP implementations come with both a
client and a server.

Note that the recent RFC detailing a "tn3270" standard is *not* the one
that is actually in general use. The RFC has not yet been implemented
anywhere that I know of (unless someone inside IBM has done so). I'm
not going to do it until I have a server I can test against...
