Joe,
Try the other suggestions mentioned in this thread (RTS/CTS set from
perferences, at least 19.k baud set from preferences, do no multitasking
while downloading, etc.). The problem is that the 68000 just doesn't have
the horsepower to keep up at 9600 much less 14.4k baud. The problem isn't
with your modem but with your computer's ability to take the data from
your serial buffer before it overflows (and you lose characters). If you
have a non-error correcting protocol you can use (ie, ymodem-g) try that
if the other modem is also a v.42 modem. You'll eliminate a layer of
(software) error checking with the protocol and let the modems handle the
error checking and retries as they were designed to. This just may give
you the extra "oomph" you need. As, with whatever term program you're
using, if they have an option of running in multiple colors, chose the
least amount (1 bitplane would be the best) — keep the system overhead
down as much as possible.
