S-Register Definitions

S0—Auto-Answer Ring Number
S1—Ring Counter
S2—AT Escape Character (User-Defined)
S3—Carriage Return Character (User-Defined)
This register determines the number of rings the modem will count before
automatically answering a call. The user can disable autoanswer by entering zero.
When autoanswer is disabled, modem can answer only with the A command.
Range: 0—255.
Default: 0.
Base Unit: 1 ring.
S1 is incremented each time the 56K Softmodem detects a ring signal on the
telephone line. S1 is cleared if no rings occur over a six second interval. This
register is read-only.
Range: 0—255.
Default: 0.
Base Unit: 1 ring.
S2 holds the decimal value of the ASCII character used as the escape character.
The default value corresponds to an ASCII +. The escape sequence allows the
modem to exit data mode and enter command mode when on-line. A value over
127 disables the escape process, i.e., no escape character will be recognized.
Range: 0—255.
Default: 43 (+).
Base Unit: ASCII.
S3 sets the character used to terminate command line and result codes. Note:
This register value is not stored with the &W command.
