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.
