For me, I was trying to download web pages from a GSM modem, all the
"programming" of the unit is via web pages, but there's no download
facility!!

Anyhow it comes with it's own Server program and you connect through a serial
port. You them log on through a browser using <http://localhost:5000>.

HTTrack worked fine on XP but not Win 7 Pro, I had to type 127.0.0.1:5000 as
the URL
