Fig. 3-1 S-Register Summary
3.2 Glossary of S Registers
S0 Number of Rings Before Auto Answer
S0 determines the number of rings that must be received before the modem automatically answers an
incoming call. For example, when S0=3, the modem automatically answers after the third ring. When S0=0,
the modem does not automatically answer an incoming call; it stays on-hook until the A command is issued
manually to answer the incoming call.
Range: 0 - 255 rings
S1 Ring Count
S1 automatically increments its value by one each time the modem receives a ring while in the command
state. S1 is reset to zero if no ring is detected within 8 seconds.
Range: 0 - 255 rings
S2 ASCII Value of Escape Character
S2 stores the ASCII value of the escape character. Setting register S2 to a value greater than 127 disables
the escape command and you cannot return to the command state. With escape disabled, in the on-line state
the modem cannot hang up until the power is turned off or the remote modem hangs up.
Range: 0 - 255, ASCII decimal.
S3 ASCII Value of Carriage Return
S3 stores the ASCII value of the carriage return character. (Pertains to asynchronous operation only.)
Range: 0 - 127, ASCII decimal.
S4 ASCII Value of Line Feed Character
