If the IIe is unenhanced then you will most likely drop characters at
19,200 bps, especially if the data is scrolling the text display.
However, if the IIe is enhanced, the chances of dropped characters are
much less.  If you accellerate your IIe and/or add a fast hard drive
for downloading to, you will probably get even less dropped
characters.

Also, the Super Serial Card has a problem with hardware handshaking
where it will cut off a character partway through transmitting it if
the handshaking line tells it to stop sending.  This can be fixed but
I don't remember the details.  I know adding a TurboASB to the Super
Serial Card fixed this problem but I don't know if any are still
available.

I think that covers it.  If anyone has anything to add or correct,
feel free.  :-)
