The pager, so far, works fine on all DEC crts that i have tried, except for VT100's marked VT100-AA. If i page up and down several times, the vt100 gets extremely confused about what its scrolling region is and where to put the next line of text. This problem persists even upon exiting TPU. Doing something like $ DIR/COLUMN=1 ! or any command with plain text output cause the screen output to jump from one line to another without much relation to screen order. I can get rid of the problem by SET TERM/NODEC_CRT, but this causes a significant loss in screen efficiency. (many users will probably be running at 1200 baud, and redrawing the screen for single line motions is not really acceptable). Has anyone else noticed this problem (i assume it is just a non-compatible firmware version in an older vt set) and does anyone have a solution or work-around? (other than "get rid of the terminals", or "convert to unix"); --stephen dowdy
