CONNECTING PLDT WEROAM ON LINUX Test Machine: OS: OpenSuSE 10.3 32-bit usb_modeswitch --> http://www.draisberghof.de/usb_modeswitch/ Check the list of supported devices. libusb, comgt or gcom --> prerequisites to control your 3G/GPRS cards. Test Device: ZTE MF620 HSDPA data card. HOWTO: Note: Unplug your device until the configuration is ready. 1.Install the usb_modeswitch #> tar jxvf usb_modeswitch-0.9.4.tar.bz2 #> cd usb_modeswitch-0.9.4 #> ./compile.sh #> cp usb_modeswitch /sbin or #> cp usb_modeswitch /usr/sbin 2. Copy the usb_modeswitch.conf to /etc. You can also use the updated version found in http://www.draisberghof.de/usb_modeswitch/. 3. For ZTE MF620, comment out the designated configuration for the said device, or enter the following at the bottom of the file: DefaultVendor= 0x19d2 DefaultProduct= 0x2000 TargetVendor= 0x19d2 TargetProduct= 0x0001 MessageEndpoint=0x04 MessageContent="55534243123456780000000000000600000000000000000000000000000000" 4. Create a new udev rule for ZTE MF620 device. ACTION!="add", GOTO="ZTE_End" SUBSYSTEM=="usb", SYSFS{idProduct}=="2000", SYSFS{idVendor}=="19d2", GOTO="ZTE_ZeroCD" SUBSYSTEM=="usb", SYSFS{idProduct}=="0001", SYSFS{idVendor}=="19d2", GOTO="ZTE_Modem" LABEL="ZTE_ZeroCD" #RUN+="/sbin/rmmod usb_storage" LABEL="ZTE_Modem" RUN+="/sbin/usb_modeswitch -d 1 -v 0x19d2 -p 0x2000 -V 0x19d2 -P 0x0001" RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0001", MODE="660", GROUP="dialout" MODE="660", GROUP="tty" LABEL="ZTE_End" 5. Install comgt and libusb in case not yet done. 6.create a file named /etc/ppp/peers/pldt /dev/ttyUSB0 nobsdcomp novj refuse-chap nodeflate ipcp-accept-local ipcp-no-address ipcp-no-addresses ipcp-max-configure 20 user [EMAIL PROTECTED] password pldt crtscts modem noipdefault replacedefaultroute defaultroute lock noauth connect '/usr/sbin/chat -f /etc/ppp/peers/pldt.chat' ipcp-restart 8 ipcp-max-configure 50 ipcp-accept-local ipcp-accept-remote usepeerdns 7. Then create a file named /etc/ppp/peers/pldt.chat ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT "NO DIALTONE" "" ATZ OK AT+CGDCONT=1,"IP","weroam" OK ATDT*99# 'CONNECT' '\c' 'TIMEOUT' '20' 8. Now plug your ZTE MF620 device and on root console, type: #> tail -f /var/log/messages Check for the following log messages which indicates that Linux properly detects the device. Jun 12 16:19:26 linux kernel: usb 1-1: new device strings: Mfr=1, Product=2, SerialNumber=0 Jun 12 16:19:26 linux kernel: usb 1-1: Product: ZTE CDMA Technologies MSM Jun 12 16:19:26 linux kernel: usb 1-1: Manufacturer: Qualcomm, Incorporated Jun 12 16:19:26 linux kernel: usb 1-1: configuration #1 chosen from 1 choice Jun 12 16:19:26 linux kernel: usbserial_generic 1-1:1.0: generic converter detected Jun 12 16:19:26 linux kernel: usb 1-1: generic converter now attached to ttyUSB0 Jun 12 16:19:26 linux kernel: usbserial_generic 1-1:1.1: generic converter detected Jun 12 16:19:26 linux kernel: usb 1-1: generic converter now attached to ttyUSB1 Jun 12 16:19:26 linux kernel: usbserial_generic 1-1:1.2: generic converter detected Jun 12 16:19:26 linux kernel: usb 1-1: generic converter now attached to ttyUSB2 9. Close the tail of /var/log/messages by pressing CTRL-C on the keyboard. 10. Execute the comgt or gcom command. #> comgt -d /dev/ttyUSB0 Check for the following log to confirm if Linux successfully configure your device. SIM ready Waiting for Registration..(120 sec max).. Registered on Home network: "Smart Communications Inc.",2 Signal Quality: 16,99 11. Then execute the pppd script afterwards. #> pppd call pldt 12. The only problem with the procedure is that it cannot configures the default gateway or the network routing is not properly configured. I fixed it by adding the following command in OpenSuSE: #> /etc/sysconfig/network/scripts/ifup-route <IP addr of PPP0> or #> route add default gw <IP addr of PPP0> 13. Test your internet connection. |
