Help tweaking settings for big transfer
                I am setting up a new WinXP machine at school and I want to transfer a big directory full of data files and folders from my Linux server at home.  When I open a Cygwin shell and scp stuff it doesn't seem to have any trouble (I transferred one directory of about 20 MP3 files).  When I use scp (v3.8.2 build 330) to copy this directory, I seem to constantly be prompted to retry or reconnect.  Are there some settings I can tweak to get it to be more robust?
Also, where can I tell scp to send "keepalive" pings like in putty?
