AT&S
This command defines the management of DSR (C107) criterion present on the modem serial port.
If controlled (AT&S1), the DSR ON indicates a connection with a remote device. When OFF it
indicates the disconnection with the remote modem. If forced (AT&S0), regardless of the status
(connected/disconnected), the DSR is always ON.
Note: Data Set Ready can be controlled in DATA and FAX modes only
