I get on the net

modprobe cdc-acm
/usr/sbin/pppd connect '/usr/sbin/chat -v "" "AT&F" OK "AT+CGDCONT=1,\"IP\",\"LEMONINTERNET\"" OK "AT+CGATT=0" OK "ATDT*99#"' noauth /dev/ttyACM0 115200 defaultroute noipdefault user ppp usepeerdns

AT+CGATT=0 I believe is same as pppd option updetach.

I want to pipe ppp0 to wlan0 & Ad-Hoc

Setup dnsmasq
pppd options
defaultroute, noipdefault, usepeerdns
problem ?

Please help if you can.
I should write a mini-howto later, what with all this progressive mobile stealth occurring, hope we're not negative electromagnetic spectrum.
