I use uupc on my Amiga to talk to uucp on my Unix system at 9600 baud.  The
nice thing about that is you don't have to attend the file transfers and if
a transfer screws up or dies, the originator (Unix or the Amiga) still knows
what files haven't been sent and will resume on the next connection.  Being a
windowed protocol, uucp will achieve higher speeds than XMODEM, YMODEM and
non-sliding-windows kermit (lots of kermits seem to have problems with
binary data or have to quote 8-bit chars in a two-for-one arrangement -ick)

Also, I have successfully done XMODEM and Kermit transfers between the Unix
system (386) and the Amiga at 19200 baud.

Finally, even with error-correcting modems, I'm not sure that it's a good idea
to not do end-to-end error checking in software because data can still glitch
along the path that's not between the modems.
