I don't know if this is a dumb question or if it's a case of dumb
terminal.

Is there any way to convince an IBM 3151 (or 3153 emulating a 3151) to
scroll backwards (up)? So far, the only way I can make it work is to set
the 3153 up to emulate a DEC VT series (100, 220, or 320). So obviously
the hardware can do it, but apparently the termcap entries for the 3151
don't support it.

I just find it very odd that I need to set up a 'current' generation
terminal to emulate a discontuned competitor's terminal to get it to
scroll. (And, up through AIX 5.1, there doesn't seem to be AIX support for
the 3153 -- you've got to pick some other terminal!)

Current? 3153 WDFM 2002/12/20. And I can't remember there ever being an
AIX terminfo for a 3153, you used "export TERM=3151". And "scroll
backwards" means a lot of different things in the ascii world, depending
on what application you are talking to. For example, was that numpad-9
or Page-Up you were pressing? For better or worse, the IBM terminals
didn't fix their function to the VT line.

And termcap isn't "supported" under AIX - only terminfo.
