| automatically answers a call. Set “S0=0” to disable auto- |
|
|
|
| answer mode. |
|
S1= |
| 0 - 255 | Count the incoming rings and store the value to this register. | 000 |
|
|
| The value of this register is incremented with each ring. If no |
|
|
|
| rings occur over an 8 sec. interval, this register is cleared. |
|
|
|
| User can read but should not change this value. |
|
S2= |
| 0 - 255 | S2 holds the decimal value of the ASCII character used as | 043 |
|
|
| the escape character. The default value (043) corresponds to |
|
|
|
| an ASCII character “+”. A value of 128 to 255 disables the |

|
| escape process, i.e., no escape character will be recognized. |
|
S3= |
| 0 - 127 | Hold the decimal value of the Carriage Return <CR> | 013 |

|
|
|
| used. |
|
S5= |
| 0 - 32, | Hold the decimal value of the character recognized as a | 008 |
|
| 127 | backspace. The modem will not recognize the backspace |
|
|
|
| character if this register is set to a value greater than 32. |
|
S6= |
|
| Set the length of time, in seconds, that the modem must wait |
|
|
|
| (minimum 2 seconds even if the value is less than 2) after |
|
|
|
| going |
|
|
|
| number. |

|
| 4 - 65 | For Japanese version. | 004 |
S7= |
|
| Set the time, in seconds, that the modem must wait before |

|
|
| hanging up because carrier is not detected. |
|
|
| 1 - 255 | For international version. | 050 |
|
| 35 - 59 | For Japanese version. | 050 |
S8= |
| 0 - 65 | Set the time, in seconds, that the modem must pause when | 002 |
|
|
| the “,” dial modifier is encountered in the dial string. |
|
S10= |
| 1 - 255 | Set the length of time, in tenths of a second, that the modem | 020 |
|
|
| waits before hanging up after a loss of carrier. |
|
S11= |
| 50 - 150 | DTMF duration and inter digit delay. Set the duration and | 095 |
|
|
| spacing, in |
|
S12= |
| 0 - 255 | Define the maximum period, in | 050 |

|
|
|
