DSR behavior
This command determines how the INSYS Modem 56k Small INT 2.0 treats its DSR
(CT107) output.
AT&S0 DSR always ON (default).
AT&S1 DSR ON after a response tone has been detected; DSR OFF when no car-
rier is detected any more.
Selects the transmission speed at the serial interface.
The settings can be selected with this command. This will, however, not switch off the
automatic detection. As soon as an AT is recognized, the serial interface will set itself to
the recognized speed and protocol.
If no AT is sent, the selected speed is maintained until a hardware reset is performed.
If the selected speed should be maintained longer, it must be stored with AT&W.
This command will not change the registry S23! It only changes if the
automatic speed detection is used.
AT*S0 Maintaining the current speed.
