I've only used scp once and I have a few questions about "convenience
features" of scp. The location I'll be at for the next several months
has an unreliable dial-up connection and the power goes down
frequently.

1) If the power fails on my computer when I'm doing a very large file
transfer with scp, after a reboot and re-establishment of the ssh
session, can scp simply resume the file transfer where it was left off
or does it have to start over from the begining?

2) can multiple connections be opened to increase the speed of the scp
file transfer?

3) would these features depend only on the underlying protocols or
technology and not scp itself?

4) if not (3), are these types of features not standardized or in the
specification? Therefore one implementation of scp could have these
features while another implentation does not?

5) what underlying protocols does scp rely on?

any information would be helpful
