ister whose setting is to be displayed.
S0—Auto-Answer Ring Number
This register determines the number of rings the modem will count before automatically answering a call. The user
can disable auto-answer by entering zero. When auto-answer is disabled, the modem can answer only with the A
command.

over a six second interval. This register is read-only.

S2—Escape Character (User-Defined)
S2 holds the decimal value of the ASCII character used as the escape character. The default value corresponds to
