11.5 S4 - Line Feed Character

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.

Range: 0-127, ASCII decimal

Default: 10 (Line Feed)

11.6 S5 - Backspace Character

S5 sets the character recognized as a backspace. Pertains to asynchronous operation only. The

modem will not recognize the Backspace character if it is set to a value that is greater than 32

ASCII. This character can be used to edit a command line. When the echo command is enabled, the

modem echoes back to the local DTE the Backspace character, an ASCII space character and a

second Backspace character; this means a total of three characters are transmitted each time the

modem processes the Backspace character.

Range: 0-32, ASCII decimal

Default: 8 (Backspace)

11.7 S6 - Wait Time before Blind Dialing or for Dial Tone

S6 operation is country dependent.

1. Sets the length of time, in seconds, that the modem will wait before starting to dial after

going off-hook when blind dialing. This operation, however, may be affected by some ATX

options according to country restrictions. The “Wait for Dial Tone” call progress feature (W

dial modifier in the dial string) will override the value in register S6. (US models.)

2. Sets the length of time, in seconds, that the modem will wait for dial tone when

encountering a “W” dial modifier before returning NO DIAL TONE result code. (W class.)

The modem always pauses for a minimum of 2 seconds, even if the value of S6 is less than 2

seconds.

Range: 2-255 seconds

Default: 2

11.8 S7 - Wait Time for Carrier, Silence, or Dial Tone

S7operation is country dependent.

1. Sets the length of time, in seconds, that the modem will wait for carrier before hanging up.

The timer is started when the modem finishes dialing (originate), or 2 seconds after going

off-hook (answer). In originate mode, the timer is reset upon detection of answer tone if

allowed by country restrictions.

2. Sets the length of time, in seconds, that modem will wait for silence when encountering the

@ dial modifier before continuing with the next dial string parameter.

3. Sets the length of time, in seconds, that the modem will wait for dial tone when

encountering a “W” dial modifier before continuing with the next dial string parameter. (US

models.)

Range: 1-255 seconds
