This patch adds a chat script and makes some modifications to
/lib/network/3g.sh to enable seamless use of CDMA/EVDO modems in
addition to the existing GPRS/UMTS support. Modifications to 3g.sh
are:
- Added 'chat' variable to point at the appropriate script
- Added 'evdo' and 'cdma' as acceptable 'service' values, and skip
the whole gcom initialization bit
- Changed pppd connection speed from 460800 to more widely supported
115200; in my experience, this is not your actual connection speed,
but at what speed pppd sends setup commands to the interface.
This kinda eliminates the need for /etc/ppp/3g.connect - I think I've
replaced that functionality, but in a slightly more standardized
method, using the 'connect' variable understood by PPP.
