Modify AT&T's suggestion for using pppd to connect to their wireless network.

Tested on beaglebone with sierra 250 from Ting. Basically, one just
dials ATD*99***1# and everything works. On older networks, use the
777 number instead.
I didn't know exactly what chat did or how it was used until this
project, which is well after I wrote
unapy. chat seems to be an
elegant solution, but it makes conditional auditing and reporting
somewhat painful if you don't love shell scripts. unapy or a similar
framework in ruby or coffeescript (for node) might be handy in the
future? There is some value in being able to audit and monitor the
modem itself.
Symlinking /etc/ppp/peers/provider -> /etc/ppp/peers/gprs will
enable starting properly such that pon and poff work. (No joke.)
$ pppd call gprs
Note: This tells the PPPD dialer to call the gprs script, which in turn calls gprs-connect-chat and gprs-disconnect-chat as necessary.
Attempt to browse.
If unable to resolve url's it's likely due to PPPD not updating /etc/resolv.conf with the correct DNS servers.
To fix this, back up /etc/resolv.conf and issue the following command:
echo - e "nameserver 10.250.1.10\nnameserver 10.250.1.11: > /etc/resolv.conf
To disconnect, press "Control-C" in the terminal window.
