Joe,
A couple of things come to mind. First of all, make SURE that you have
your serial preferences set to use "Hardware Handshaking" (also known as
CTS/RTS handshaking). If your term programs have configuration options
for this (some do, others default to what Preferences is set to), make
sure that CTS/RTS is enabled there too. You will also need to be using a
7-wire (or more) serial cable from your amiga to your modem.
A second thing to watch out for is interference from _some_ hard disk
controller boards. You can try to download files to RAM: instead. Also,
downloading direct to floppy disk can cause real problems for high-speed
transfers, as it takes a long time to write the buffer to disk.
Remember that the stock 68000 is (in relative terms) fairly slow, and
that you really are pushing things to try to keep up with high-speed
transfers. There's little margin of error, so "little" things can cause
glitches. I would try to keep "background" programs to a minimum when
attempting to do a high-speed download.
Of course, an accellerator will also help, but I suspect that you don't
particularly want to hear that one. <grin>
Hope this helps…
