Support send Chinese/English SMS by AT command.
Support RFC2217 function, the parameters of interface can be revised.

Configuration method:
1) AT command configuration.
2) software configuration

Working Mode

1. Network transparent transmission mode
In this mode, User’s device can send data to specified server by WCDMA network. G761 support 2 socket link, that is Socket A and Socket B, two links is mutual independence.
2. HTTPD Client Mode
In this mode, the data will sent to HTTP server directly, or obtain data from HTTP server. The data will sent to Web server(apache, IIS, tomcat, etc) in Http(GET/POST) mode as long as sending data in formal format. User can utilize the scripting language like PHP, ASP as database storage.
3. SMS transparent transmission mode
In this mode, user’s device can send SMS to specified phone, or transmit the SMS from phone to device. The transparent transmission between device and phone can realised by parameter setting.
4. AT command
When G761W working in any kind of mode(Network transparent transmission, SMS transparent transmission, AT command), user can send specified data, then let WCDMA switch into AT command mode.
