- "Blindingly fast" relates of course to a dataline speed which is
- many times higher than 2400bps, right?
- An opsys I like very much is also *fast* (at 56Kbps, who wouldn't
- be!), but it also does partial screen updates by comparing the data
- the old with the new data, redrawing only the differences. Still,
- they were smart enough to include a "fullscreen refresh" for "dirty"
- datalines. Not on a per-application level, but at opsys level.
-
- Now, how is this accomplished? Hopefully not covered by some
- patent?

- Glad to hear that at least somebody shares my view re this. :-)
- Does anyone have other opinions/ideas/suggestions?
