You're probably stuck.  VPLUS assumes you hav an HP-compatible terminal,
and the xterm (emulting a VT100/VT102) is *not* HP-compatible.
 
Another alternative is to investigate getting a third party Unix-based
HP terminal emulator (with or without NS-VT capabilities).
 
My old notes show two possibilities:
 
1) If you are looking for HP3000 emulation from a Unix system, you might
   look at a company called Software Licensing Corp in NV. (702) 832
   0881.  Contact: Paula Gofton
 
   They have IX/92 and IX/Connect, which are HP terminal emulators and NS/VT
   transport products for HP-UX, SCO, and Sun.  From talking with Paula, the
   original roots (way back when) of Reflection and MiniSoft 92 spouted from
   a common base.  They were also in the deal and did the Unix version.

2) Wildwood Software (?)
   Contact: Teodor at (408) 927-6438 ... you can mention my name, if
   desired.  He wrote and is maintaining/enhancing an HP2392 terminal
   emulator for Unix.  Sorry I don't have the full set of phone numbers for
   his company, or his email.
 
Finally, Dan Hollis freeware vt3k may be of help as well, although it is
a *transport* mechanism, not an *emulator*.
