S3
13
Carriage Return Character: S3 specifies the AT command string terminator and
modem response code terminator. The factory default is a <CR> or carriage return
(ASCII decimal 13).
Range: 0–127
Default: 13 (Carriage Return)
S4
10
Line Feed Character: S4 specifies the line feed character, which is used for verbose
(text) modem result codes.
Range: 0-127
Default: 10 (line feed)
S5
8
Backspace Character: S5 specifies the backspace character that is used to delete
the last-entered character. After receiving a backspace character, the modem sends
three characters to the DTE: a backspace character, a space character, and then an-
other backspace character.
Range: 0–32, 127
Default: 8 (BS)
S6
2
Wait Before Blind Dialing: S6 specifies the amount of time that must elapse after
the modem goes off-hook before the modem starts dialing the first telephone num-
ber. The modem waits for at least 2 seconds before dialing the first number, even if
S6 is set for a value less than 2. S6 is only used for result code type commands X0,
X1, and X3 (that is, blind-dialing types of result codes). Result code types X2 and X4
enable dial-tone detection and ignore the contents of S6.
Range: 2–255 seconds
Default: 2 seconds
S7
60
Wait for Carrier/Dial Tone: S7 specifies the length of time that the modem waits to
detect the remote modem carrier after dialing the telephone number. If the remote
modem carrier is not detected within the S7 time limit, the modem hangs up and
sends a ‘NO CARRIER’ response code to the DTE. If the remote modem carrier is
detected, the modem goes into online data mode and sends a “CONNECT” mes-
sage to the DTE.
S7 also specifies the time duration for the ‘@’ (wait for quiet answer) dial modifier.
Range: 1–255 seconds
Default: 60 seconds
S8
2
Pause Time for Dial Modifier: S8 specifies the length of time that the modem paus-
es during the dialing process each time the ‘,’ dial modifier is detected in the dialing
string.
Range: 0–255 seconds
Default: 2 seconds
