As to terminal emulators that can do graphics: I have never seen a
freely available package capable of ReGIS. A few of the commercial
products can/could do it, such as WRQ Reflection, SmarTerm 340, Rumba,
DCS EM340, poly-STAR/GW, and KEAterm:

Also (according to the documentation), dxterm (DEC term). I don't have a test
for that, but thought it implied that dxterm would support soft fonts as well.
But it doesn't (or else the test I wrote against a vt420 is too fragile to work
with a second terminal ;-)
