From 738d610209c81288218c31b1edd99e20449550ae Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 2 Feb 2008 01:21:31 +0000 Subject: Add CDMA/EVDO support to comgt package 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.
