Description
S101 determines how the modem reports the occurrence of distinctive ringing signals. The values were selected so a value of 0 would enable conventional ringing detection and reporting.

Distinctive ringing may occur in one of several types as follows:

Type   Description                                         


A      1 long on and long off (Morse T)                    


B      2 rings (Morse I, M, A, or N)                       


C      2 short, 1 long, long off (Morse U)                 


D      1 short, 1 long, 1 short, long off (Morse R)

The values for S101 have the following meanings:

0    1       Enable "RING <type>"reporting instead of         


            "RING".                                                


1    2       Disable reporting of type A ringing.                          


2    4       Disable reporting of type B ringing.                          


3    8       Disable reporting of type C ringing.                          


4    16      Disable reporting of type D ringing.                          


5    32      Disable reporting of type U (unidentified) ringing.

Examples:

S101=0 commands the modem to detect all ringing cadences and report them with "RING"result code.

S101=1 enables the RING <type>result codes; all ringing types will be reported.

S101=58 tells the modem to report only ringing type B, with the RING result code.

S101=59 tells the modem to report only ringing type B, with the RING <type>result code.

S101=62 disables all ringing detection.

Note: RI and AA behave as in older modems that do not support detection of distinctive ringing.
