5 Status Registers & Result Codes

In most bit-mapped S-registers, the default bit value is 0. Non-0 default values are followed by an asterisk. Some bits are reserved for factory use and should not be changed.

S-Register Definitions

S0 - Number of Rings to Auto-Answer

Sets the number of the rings required before the modem automatically answers a call. Setting this register to zero disables auto-answer mode.

S1 - Ring Counter

S1 is incremented each time the modem detects a ring signal on the telephone line. S1 is cleared if no rings occur over an eight second interval.

S2 - Escape Character

S2 holds the decimal value of the ASCII character used as the escape character. The default value corresponds to an ASCII '+'. A value over 127 disables the escape process, i.e., no escape character will be recognized.

S3 - Carriage Return Character

Sets the command line and result code terminator character. Pertains to asynchronous operation only.
