H – Hang-Up command
The command ATH (or ATH0) is used by the application to disconnect the remote user.
In case of multiple calls, all calls are released (active, held and waiting calls).
The specific Wavecom command ATH1 has been appended to disconnect only the out-
going call. It can be useful in case of multi communication.

A – Answer a call
When the GSM module receives a call, it set the RingInd signal and sends to the appli-
cation the ASCII string ”RING” or ”+CRING: <type>” if cellular result code (+CRC) is
enabled. Then it waits for the application to accept the call.
