I have read the other threads here about PPP, and have pored over the Multitech
modem
manual, but I don't understand the PDP Context command, +CGDCONT.
What is the DNS name given as parameter 3 for? (In the example below,
internet3.voicestream.com).
The manual states that parameter 3 is "a string that identifies the modem in
the address
space applicable to the PDP".
Can I invent anything I like, leave it blank? It's not a destination address,
is it?
Given that you use pppd to control the connection, why is parameter 2 set to IP
instead of
PPP?
Even with 5 years of GSM experience, I am really struggling! Is there a good
guide to GPRS
somewhere between Wikipedia and the GSM standards?
