I have added support for Panasonic ToughBook CF-F9 U3G GOBI2000 to FreeBSD U3G kernel module [1]. I have added firmware for Panasonic CF-F9 and HP EliteBook 2740p along with gobi_loader updates [2] that are required for 3G modems to work.

At first U3G module will create /dev/cuaU0 interface for QDL firmware load, then after successful firmware load device will reload itself to a modem mode and U3G module will provide additional /dev/cuaU0.* nodes for operations (/dev/cuaU0.2 is the AT command intarface).

In order for this modem to work on FreeBSD you also need to tune some configutation files:

  • /etc/devd.conf:
    attach 100 {
     match "vendor" "0x04da";  #adjust your device VID
     match "product" "0x250e"; #adjust your device PID
     action "/usr/local/sbin/gobi_loader -2000 /dev/cuaU0 /boot/firmware/gobi/";
    };
    
  • /etc/ppp/ppp.conf:
    default:
     set log Phase Chat LCP IPCP CCP tun command
     ident user-ppp VERSION
     set device /dev/cuaU0.2
     set phone *99\#
     set redial 5 10
     set speed 115200
     set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
               \"\" AT AT-OK-AT ATH OK ATZ OK ATE1Q0 OK \
               AT+CFUN=1 OK-AT-OK \
               AT+CPIN? READY-AT+CPIN=\"YOUR_PIN_HERE\"-OK \
               AT+CGDCONT=1,\\\"ip\\\",\\\"internet\\\" OK \
               \\dATDT\\T TIMEOUT 40 CONNECT"
     set timeout 20
     enable dns
     set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.255 0.0.0.0
     add default HISADDR
    

You now should be able to use your 3G modem connection with ppp -ddial, after you add your local user to the dialer group with pw groupmod dialer -m your_user_name. Remember to have U3G compiled in. Enjoy the Internets! 🙂

If you want to use GSM/3G/LTE modem on your FreeBSD box you need to use PPP and following configuration:

default:
 set log Phase Chat LCP IPCP CCP tun command
 ident user-ppp VERSION 
 set device /dev/cuaU0
 set phone *99\#
 set redial 5 10
 set speed 115200
 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
           \"\" ATH OK ATZ OK AT OK-AT-OK ATE1Q0 OK \
           AT+CFUN=1 OK-AT-OK \
           AT+CPIN? READY-AT+CPIN=\"1234\"-OK \
           AT+CGDCONT=1,\"ip\",\"internet\" OK \
           \\dATDT\\T TIMEOUT 40 CONNECT"
 set timeout 10
 enable dns
 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.255 0.0.0.0
 add default HISADDR
