Debug 3G dialing on the vro

Create a 3G dialing Image
1. to configure the kernel, add
Easy NFS debugging
Usbserial load driver
2. Configure other options: vendor
3G add dialing tools and scripts
It is best to add Netcat to busybox for debugging.
3. modify the configuration file and add support for additional modules. Therefore, we define the following:
Sbin/3G. Sh
Etc_ro/web/Internet/WAN. asp
920 <option value = "MU-Q101" id = "MU-Q101"> nu MU-Q101 </option>
+ <Option value = "mc8630" id = "mc8630"> ZTE mc8630 </option>
921 <option value = "HUAWEI-E169" id = "e169"> Huawei e169 </option>
Elif ["$ Dev" = "HUAWEI-E169"]; then
Usb_modeswitch-C/etc_ro/USB/usb_modeswitch_HUAWEI-E169.conf
+ Elif ["$ Dev" = "mc8630"]; then
+ Echo "We use mc8630, no need usb_modeswitch"
Elif ["$ Dev" = "HUAWEI-E169"]; then
Vend_id = "0x12d1"
Prod_id = "0x1001"
+ Elif ["$ Dev" = "mc8630"]; then
+ Vend_id = "0x19d2"
+ Prod_id = "0 xfffe"
-Insmod usbserial vendor = $ vend_id Product = $ prod_id
+ Insmod/etc_ro/usbserial. Ko vendor = $ vend_id Product = $ prod_id
If ["$ Dev "! = "OPTION-ICON225"]; then
-Config-3g-ppp.sh-P pass-u user-M $ modem_f-C generic_conn.scr-D generic_disconn.scr
+ Config-3g-ppp.sh-P card-u card-B 115200-M $ modem_f-C my_conn.scr-D generic_disconn. SC
Pppd call 3G
4. Compile my_conn.scr
-Send "ATD * 99 # ^ m"
+ Send "ATD #777 ^ m"
-Set com 115200n81
+ Set com 3366n81
-Send "at + cfun = 1; + cgdcont = 1, \" IP \ ", \" Internet \ "^ m"
-Waitfor 10 "OK", "Err", "error"
Try remeber {
Vendor = 0x19d2 Product = 0 xfffe
+ Config-3g-ppp.sh-P card-u card-B 460800-M $ modem_f-C generic_conn.scr-D generic_disconn. SC
}
4. Compile and load the image. on the web page, select the 3G module.
