As far as I understand, there are several Java implementations of
HP compatible terminal emulators. Some might be applets, some might
be standalone programs. Minisoft Javelin and WRQ EnterView (called
Reflection for the Web by now) come to mind. TeemTalk from Pericom
might be a third contender, but I don't recall whether they do HP
emulation with NS/VT connectivity.
