Chapter 14 – Status Registers

Some of these registers relate to the call progress timing at the IWF with the PSTN connection. These are noted

below using the (Remote) tag.

Table of S-Registers

Reg. Description Range Default Units

0 Auto answer

The modem auto answers after a delay specified by S0.

If S0=0, then auto answer is turned off.

The delay is equivalent to [<value> - 1] x 6 seconds.

Examples:

1 = no delay

3 = 12 seconds

0–255 000 (n-1)*6 s

Carriage Return Character

The standard end of line character used to indicate the end of an AT

command. This character is also used as the carriage return

character for framing responses and result codes in command state.

0–127

013 (CR)

ASCII

Line Feed Character

The standard line feed character sent by the modem to the host at

the end of a response or return code in command state.

0–127

010 (LF)

ASCII

Backspace Character

This register sets the character recognized as a backspace during

command entry.

0–127

008 (BS)

ASCII

6 Wait for Blind Dial (Remote)

This register denotes the wait time, in seconds, before a blind dial (no

dial tone detection).

The value of S

6 is used when the X (Result Code Select/Call

Progress Control) command is set to 1, or 3.

X settings of 2 and 4 enable dial tone detection and disable blind

dialing.

Therefore, when X is set to 2 or 4, the value of S6 is irrelevant.

Seconds

7 Wait For Carrier (Remote)

If no carrier from the remote modem is detected within the specified

time, the modem goes on-hook.

1–255

060

Seconds

8 Comma Pause Time (Dial Modifier)

(Remote)

Whenever a dial command contains the comma character, the

contents of this register specify the pause time for each comma.

0–255

002

Seconds

9 Carrier Detect Response Time

(Remote)

Specifies the time that the received carrier must be present for the

modem to recognize it and turn on Data Carrier Detect (DCD) if

applicable.

The implementation is entirely at the IWF modem.
