	You do not say how you did the download.  If you were using
kermit, this would be the expected speed, because of kermit overhead.
If you were using xmodem I would expect faster transfer.

	I use Versaterm and kermit with long packet sizes (1000 bytes).
This works well at 2400 baud (or 19,200 to my IBM-PC over a direct
line).  But long packets can kill you if you have a noisy line.
Unix kermit got long packets relatively recently, so you may have to
upgrade.

	(I have to use kermit because my connection to the unix
machine is over a LAN which interprets ^P, ^S and ^Q, and the
LAN's modem interprets ^Q and ^S without letting it get to the LAN).
