Below is everything I did to get PPP working on the 7800. Some specifics will not apply to you, as they are specific to using a GPRS modem over Tmobile, but you should be able to figure it out. NOTE especially the options file and the nolock option. hope this helps. Add the following lines to /etc/modules ppp_generic ppp_async pppoe pppox
Create file /etc/modutils/ppp:
Paste the following and save: alias /dev/ppp ppp_generic alias char-major-108 ppp_generic alias ttt-ldisc-3 ppp_async alias tty-ldisc-14 ppp_synctty alias ppp-compress-21 bsd_comp alias ppp-compress-24 ppp_deflate alias ppp-compress-26 ppp_deflate
Create file: /etc/ppp/peers/tmobile nolock user E password P connect '/usr/sbin/chat -v -s -f /etc/chatscripts/tmobile-connect' disconnect '/usr/sbin/chat -v -s -f /etc/chatscripts/tmobile-disconnect'
#the following must appear HERE instead of OPTIONS b/c of priv. status noauth
Create file: /etc/chatscripts/tmobile-connect TIMEOUT 15 ECHO OFF ABORT "NO ANSWER" ABORT "NO CARRIER" ABORT "Connection terminated." SAY "Starting GPRS Connection\n\n" ABORT "ERROR" "" ATZ OK ATE0
#TURN OFF MODEM ECHO OK ATE1 #OK "ATE0V1" #"" 'ATE1' OK AT+CPIN? READY AT+CGDCONT=1,"IP","m2m.t-mobile.com" ECHO ON OK AT+CSQ SAY "****************** SIGNAL STRENGTH *************************:\n" ECHO OFF OK ATD*99***1# CONNECT 'c'
Create file: /etc/chatscripts/tmobile-disconnect "" +++ATH0 SAY "GPRS DISCONNECTED"
Create (or modify) file: /etc/ppp/ip-up.local (this is executed upon a good ppp connection) exec /usr/local/bin/pppconnection
Create file: /etc/ppp/ip-down.local exec /usr/local/bin/pppconnection 1
Make the above 2 files executible: chmod 700 /etc/ppp/ip-up.local chmod 700 /etc/ppp/ip-down.local
Copy file /etc/ppp/options to the following: cp /etc/ppp/options /etc/ppp/options.bak
Modify file /etc/ppp/options to the following: debug #nodetach stay running #updetach #to detach once connected. For debugging purposes only.
asyncmap 0 usepeerdns
#hardware flow control #crtscts cdtrcts #if no hardware flow control is available persist #re-connect upon a failed connect
#nomagic
nopcomp nobsdcomp nodeflate noauth
defaultroute #use this if you want this device to be the main internet connection. #You would not use this if you were for somereason using ppp AND wired internet. replacedefaultroute #replaces the wired route. Replaces back when done. #add a new default route in which the peer is the gaetway
Set the Serial Port to the desire bit rate (recommended: 38400): setserial /dev/ttts4 baud_base 38400
REBOOT the system reboot
COMMANDS:
Once a good connection is made: "Ifconfig ppp0" should return values.
