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.
S5 - Backspace Character
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.
S6 - Wait Time for Dial Tone Before Blind Dialing.
Sets the length of time, in seconds, that the modem will wait before starting to dial after going
The modem always pauses for a minimum of 2 seconds, even if the value of S6 is less than 2 seconds.
S7 - Wait Time For Carrier After Dial, For Silence, or For Dial Tone After “W” Dial Modifier (US Models)
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
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.
S8 - Pause Time For Dial Delay
Sets the time, in seconds, that the modem must pause when the “,” dial modifier is encountered in the dial string.
S9 - Carrier Detect Response Time
Sets the time, in tenths of a second, that the carrier must be present before the modem considers it valid and turns on RLSD. As this time is increased, there is less chance to detect a false carrier due to noise from the telephone line.
