Data call (aka CSD) with QtExtended

[Tuan TRINH]

Hi Ed,
Just try to initiate data call but no success.

There is a strange symptom that is: If I use the same SIM but on other
mobile (Motorora Z8) I can hear the far end land-line modem sound respone
but if I use FR to call the same modem: (1) via AT commands I see no
response, both sound and response modem characters so can not use
expect(CONNECT) with ppp (2) via GUI, it drop the call.

My FR can do voice call normally.

Do you have any way to debug the status of data call while using AT
commands? I just know +CEER but it does not give much info.

Cordially,
Tuan
