Command

Default

 

Description

 

 

 

 

 

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

S5

8

the DTE: a backspace character, a space character, and then another backspace character.

 

 

 

 

Range: 0–32, 127

 

 

Default: 8 (BS)

 

 

 

 

 

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 number. 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

S6

2

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

 

 

 

 

 

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

S7

60

code to the DTE. If the remote modem carrier is detected, the modem goes into online data

mode and sends a ‘CONNECT’ message to the DTE.

 

 

S7 also specifies the time duration for the ‘@’ (wait for quiet answer) dial modifier.

 

 

Range:

1–255 seconds

 

 

Default: 60 seconds

 

 

 

 

 

Pause Time for Dial Modifier: S8 specifies the length of time that the modem pauses during

S8

2

the dialing process each time the ‘,’ dial modifier is detected in the dialing string.

Range:

0–255 seconds

 

 

 

 

Default: 2 seconds

 

 

 

 

 

Carrier Detect Recovery Time: S9 specifies how long the remote modem carrier must be

 

 

present on the telephone line before the modem detects it and turns on DCD. The greater the

S9

6

time duration, the less likely that a false carrier detection occurs due to noise on the telephone

line.

 

 

 

Range:

1–255 (1/10 of a second)

 

 

Default:

6 (equals 0.6 seconds)

 

 

 

 

 

Lost Carrier Hang Up Delay: For modes V.32 and below, S10 specifies the length of time the

 

 

modem waits before hanging up after the loss of the remote modem carrier. This delay allows

 

 

for the temporary loss of the remote modem carrier without causing the local modem to hang

 

 

up.

 

 

 

S10 reports the time in 1/10 second units beyond 20 seconds. For example, when S10 = 0, the

 

 

wait time is 20 seconds. When S10 = 100, the wait time is 30 seconds.

S10

14

In V.34 and V.90 modes, the modem automatically retries the connection for the time specified

 

 

in S10 (Plus the mode-specific base time) before hanging up. In V.34 mode, the base time is 20

 

 

seconds. In V.90 mode the base time is 45 seconds.

 

 

For all modes, the modem does not disconnect upon loss of the remote modem carrier if S10 is

 

 

255.

 

 

 

Range:

0–255 (1/10 of a second)

 

 

Default:

14 (equals 1.4 seconds plus the 20 second minimum)

 

 

 

 

 

DTMF Dialing Speed: S11 specifies the duration of dual-tone multi-frequency (DTMF) dialing.

S11

70

This register is not used for pulse dialing.

Range: 50–255 ms

 

 

 

 

Default: 70 ms

 

 

 

NOTE: An asterisk (*) denotes the factory-default setting.
