   Subject: pNN: VT100 scrolling region
   From: Frank@mindlink.bc.ca (Frank I. Reiter)

   Part of an application I am working on includes a VT100 emulator.  We thought
   this was complete until today when one of our users began using it to telnet
   into a VAX system where the default editor makes use of scrolling regions.

having been down this path recently, i would highly recommend that you
get one of the DEC programming manuals explaining use of the scrolling
regions.  there are many "shortcuts" that applications make when using
scrolling regions that  will  break  a  non-robust  terminal  emulator
implementation.  you will end up doing a lot of tweaking for different
applications as they use this functionality in different, non-obvious,
ways.
