We are working on PHS8-P gsm module with windows embedded handheld 6.5. the driver we have works well with the GSM module with formware version 3.001. but the recent module has upgraded firmware version of 3.320. we tried adding this version number as MAX firmware version in the existing driver and most of the functionalities were working fine except that the internet connection fails all the time.

The error log shows

"RilDrv: discarded response: ^SSTN 37

RilDrv: discarded response: ^SSTN 254"

Is there a way to downgrade the firmware version or even any modification available to support 3.320 ?

Is the driver source available for firmware version 3.320 ?

Thanks.
