As I remember it, VAXStations only emulate VT100s, VT220s and Tektronix
4010/4014 terminals.  

I have no experience with Tek4125 or 4129 terminals, so cannot say if
the SMG$ routines will work on a real Tek4125, etc. terminal with the
existing terminal definitions.  If they don't, a custom set of terminal
characteristics tables will have to be generated for SMG$ for these
Tek terminals (see the documentation).

The SMG$ routines do not use graphics.  They provide windowing on character
cell terminals.  Besides, doing SMG$ style windowing on a VT240 in Regis
mode would be sooo slow that... (hard to believe that the same company
which produces the fast VAXStation II/GPX also makes the VT240/VT241).

Note that the VAXStations don't emulate VT240s or VT241s either.
Makes it hard to use Datatrieve, DECslide, DECgraph, etc. etc. etc.
