- 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.
