Register Descriptions

S0 — Number of Rings Till Auto-Answer
Range
Default
Establishes the number of rings required before the modem answers the
incoming calls. Setting this register to zero disables auto-answer mode.
S1 — Ring Counter
Range
Default
Number of rings which the modem detects before it answers a call. If no
rings occur over an eight second interval, the register is cleared.
S2 — Escape Character
Range
Default
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.

Range
Default
Sets the command line and result code terminator character. Pertains to
asynchronous operation only.
S4 — Line Feed Character
Range
Default
Sets the character recognized as a line feed. Pertains to asynchronous
operation only. The Line Feed control character is output after the
Carriage Return control character if verbose result codes are used.
