Thanks to all who replied: (Frank Storbeck) (Adam Shostack) (Brian Tierney) (Kevin E Cosgrove) (Nigel O'Brian)

A common reply was to get hold of zmodem for the Sun. I tried my local
archive, and found one, which works well. It gives a much more
reliable connection than Kermit, even though large transfers frequently
fail. This is because zmodem manages to resurrect failed transfers
from the point of failure. This is what I really needed.

zmodem is not the ideal solution, but it is the best that I have come
up with so far.

Other solutions were offered:

(To which the answer is no - I haven't heard of them.)

I haven't tried this one, but it may be a good solution to a slightly
different problem.

My other gripe was:

Nobody commented on this one. On further investigation, what is
happening is that any file transferred in binary from Sun to Mac gets a
282-byte header attached which identifies it as an "Apple single-format
resource file". I have got around this by writing a filter to strip
off this stuff. Not the most elegant solution, but it works :-).
Anyone know why this happens, or whether it is unique to Microphone?
