Since I'm the person responsible for the team that built and/or brought these
products to market I'd like to first say thanks for the compliment.

A relatively minor nit I'd like to give the full names for the products referred 
to above. They are:

DEC SNA Domain Gateway-VT
and
MEP VT for DEC SNA 3270 Application Services

"MEP VT" is an INTEGRATA product sold and supported by Digital Equipment 
Corporation.

All 3270 terminals are supported including ones without EAB. But terminals
without EAB cannot display reverse video, underlining or blinking. This makes
some VT applications very hard to use. Eg applications that like to use
reverse video to delineate fields etc. There is a setup option:

SEND_ATTRIBUTES

that needs to be set to NO for non EAB terminals. This should be done 
automatically if you are using LOGMODE entry that correctly identifies the
terminal. Strange things will happen if it is set to YES.
