[nzlug] Telnet in all it's... hmm.... greatness?

[Nick 'Zaf' Clifford]

The other thing I've done in that case is use the web page interface
instead of telnet.

Believe it or not, its often easier.

Because you know the page will never change its format (unless you
upgrade its firmware), you can basically pull out anything the webpage
displays easily.

The commandToTryAndStartPPP will probably be a HTTP POST, which you can
send easily enough with a perl script.

That said, its probably "better" to use the telnet interface, as thats
kinda what it was suppose to be for.
