sigh...this is really not that hard. The secret is to scroll more than one
line at a time, if you have received more than one line of data since the
last scroll.
I wrote some PM code to do fast scrolling (in a real PM program, not el-
cheapo AVIO) about 6 years ago, but it wasn't until last year's coloradOS/2
that I cleaned it up enough to release it. That was about 1.5 years ago --
and I did release it, but I guess it didn't get much further than the
coloradOS/2 '94 cdrom. I'll post it on my bbs.
It is a _very_ dumb terminal program, and the code is meant to be explained
by me while I am giving a presentation (ie: there are but few comments in the
code).
Hint: to see how fast it can scroll, type a text file name for the port
(instead of "COM1").
