Although AT&T refuses to release source for the DMD terminal ROM and for
the downloaded layersys (for older firmware), all other DMD code is in
fact available in source form via the usual licensing channels.  There are
three DMD host packages, as follows:  One needs the "Core" package simply
to run "layers".  People who do troff-style typesetting can use the
"Text/Graphics" package.  In order to develop DMD downloaded applications,
such as the interactive interface you desire, one needs the "Application
Development" host software package.

The AT&T UNIX System Toolchest distributes Dave Prosser's "myx" terminal
emulator in their "dmd-pgmg" package.

There are two AT&T documents which one can buy separately that describe
DMD application development:
Select Code 306-142	"5620 DMD Rel. 2.0 Application Development Guide"
Select Code 306-144	"5620 DMD Rel. 2.0 Reference Manual"
The first of these comes with the corresponding DMD host software package.
(I don't remember whether or not the second comes with the software.)

There is also a 1-week DMD programming course given by AT&T at Lisle, IL
that I recommend, particulary if you're having trouble understanding the
documents mentioned above.
