Status Registers & Result Codes 41
S2 - Escape Character
S2 holds the decimal value of the ASCII character used as the escape character. The
default value corresponds to an ASCII '+'. A value over 127 disables the escape
process, i.e., no escape character will be recognized.
S3 - Carriage Return Character
Sets the command line and result code terminator character. Pertains to asynchronous
operation only.
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 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.
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 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.
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.
