GPRS networking documentation

Today I set up a Novatel Wireless Merlin G201 GPRS modem on
my NetBSD/hpcarm HP Jornada 728.
I found some things in the GPRS documentation are lacking.
(htt
p://netbsd.org/Documentation/network/gprs.html)

First thing I ran into was that you need to turn off PIN
request in the SIM card using
a mobile phone.

Second thing, the GPRS provider needs me to set an APN
(access point name),
if I don't give it the right APN I won't get the right
connection profile.
After googling and finding some linux documentation for a
different card I
figured out how that is done.
So my chat script goes like this:

ABORT BUSY ABORT 'NO CARRIER' ABORT ERROR '' ATZ OK
'at+cgdcont=1,"IP","open.internet"' OK
'ATDT*99#' CONNECT

where open.internet is the apn name for O2 in Ireland to
give me
an unfirewalled IP link.

Third thing, in my case the provider doesn't automatically
configure DNS
so I had to remove the usepeerdns option or else I got an
error about
an invalid IPCP message.
pppd[4211]: Received bad configure-rej:  81 06 00 00 00 00
81 06 00 00 00 00

I figure these 3 should probably be added to the GPRS
documentation.

Can you send a patch for the gprs.xml file?

For the record: I got a patch and have committed it to 
htt
p://netbsd.org/Documentation/network/gprs.html - it
should be online 
within an hour.
