I tracked down the NUL and changed it to a space manually, and the
whole box then transferred.

/norsh cured the ssh prompt.  I still need to give the mailbox
password (just once per connection).  The whole operation still seems
rather slow, c 20 minutes for 100Mg mailbox.  These are all going to
the same box on the server.  Again, nobody is using much CPU.  I
suspect I may need to tune my Cyrus server.

I take it from your earlier response that even if I set up ssh so I
had passwordless login I would still need to answer a password prompt
for the mailbox.  So I need to work on my expect script.

Thanks for your help.

P.S. For those  who find this in the archive.  I used the /debug
option to narrow down which message was causing the trouble.  However,
the output is a little misleading because of the asynchronous
operations.  The debugging shows the messages as they go in; the error
about the NUL actually referred to a somewhat earlier message (I
think).
