Creating PPP Configuration Files and Scripts

AT&T and AT&T-like carriers and Verizon require different modem configurations for data connections. This
example addresses the differences using separate PPP chat scripts.
Copy and paste options, peer, and carrier specific chat scripts from the respective code blocks in Example PPP Files
into the respective new files and locations indicated:
vi options
$ vi l4g2d_peer
$ vi l4g2d_att_chat
$ vi l4g2d_vzw_chat
$ sudo mv /etc/ppp/options /etc/ppp/options.orig #backup original
$ sudo cp ./options /etc/ppp/options
$ sudo cp ./l4g2d_peer /etc/ppp/peers/
$ sudo cp ./l4g2d_att_chat /etc/chatscripts/
$ sudo cp ./l4g2d_vzw_chat /etc/chatscripts/
