title: Is it possible to read signal quality from GSM/CDMA modems while connected?
body: <p>I know I can communicate with GSM/CDMA modems using AT commands. However, as far as I know this doesn't work when connected - is there a way to read status information (signal strength, GSM/HSDPA mode etc) while connected?</p>
  
  <p>I am not sure if modemmanager will produce the information, I tried it with Nokia phone and it didn't - however I would like it mostly for the Qualcomm chipset modems (Huawei), does anyone have any experience reading realtime signal information from these modems?</p>
