- A couple days ago I asked some VT100 questions, and got these answers (thanks
- folks) :
-
- > 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" ?
-
- It means line 1-22.
-
- > 2) Should a clear screen code clear the scrolling region only, or the
- > entire
- > screen? How about a clear to end of screen?
-
- Whole screen.
-
- > One more vt100 question: Can anyone tell me what an ESC \ sequence is
- > supposed to do?
-
- It is a VT52 "Exit HOLD SCREEN mode". I don't know what a HOLD SCREEN mode
- is, but that's apparently what the coe is.
-
- Thanks again to those helpful folks who answered my questions.
-
- Frank.
