- I am tring to install PHS8-P modem. yesturday i was able to comunicate with modem throuh computer (win 7). And sent some AT comands by Hyper Terminal. But to day computer cant dedect USB port and modem. Can someone help to me?
2. Data logger shows modem is offline. I think so may be firmware is old. I have got new version but how to download to the modem. Do we need to use AT comands. If yes which of them is usefull for me.
To update the firmware you need to have the direct access to the module's interface (USB or RS232). Then you have to do the update on the modem port. Send the command AT^SQPORT? with some terminal program to test the port type. You may need to change the physical port or the module settings - please see AT^SDPORT command in the documentation. If the configuration is correct you can start gWinSwup. Please also check in Device Manager if the proper drivers are installed.

how to communicate with modem after firmware update?
As you need to update the firmware on the modem port you may need to change port assignmenst with AT^SDPORT command to assign the modem interface to the interface you are uisng. Please see the AT commands specification document for more details.
After the successful update the module should work as before. You should then restore the previous SDPORT setting.
