- 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.
-
- My understanding is that the code ESC [n1;n2r sets the scrolling region to
- lines n1 through n2 inclusive, but there are two things I do not know:
-
- 1) Does ESC [;22r mean "scroll lines 0 through 22" or does it mean "Set the
- bottom scrolling line to 22, leave the top line as it is set already" ?
-
- 2) Should a clear screen code clear the scrolling region only, or the entire
- screen? How about a clear to end of screen?
-
- I will be ever so grateful if somebody could answer these questions for me.
-
- Frank.
