I am developing a connection manager app for my company. The hardware is a Getac RX10 with an embetted EM7305 modem.
We had issues with the Apn-settings on the windows network options. Sometimes the Apn settings such as apnuser and password disappear from the windows settings.
So we decided to handle it on our own. I can´t figure out how I can set the apnuser and password.
Currently I communicate with the modem via COM-Port and AT commands.
I checked the documentation and couldn´t find any command to handle the username and password.
