S3 Return Character

Unit: Decimal

Range: 0–127

Default: 13 (^M)

S3 defines the carriage return character by its decimal ASCII code. The default setting is the ^M character (decimal 13), which is the code for ENTER on most keyboards. S3 may be set for any ASCII character.

Note: If you change the S3 value, you must make corresponding changes in your data communications software.

S4 Line Feed Character

Unit: Decimal

Range: 0–127

Default: 10 (^J)

S4 defines the line feed character by its decimal ASCII code. The default setting is ^J (decimal 10), which is the code for the line feed key on most keyboards that have such a key. S4 may be set for any ASCII character.

S5 Backspace Character

Unit: Decimal

Range: 0–127

Default: 8 (^H)

S5 defines the backspace character by its decimal ASCII code. The default setting is the ^H character (decimal 8), which is the code for BACKSPACE on most keyboards. S5 may be set for any ASCII character. Setting S2 to a value greater than 32 disables the backspace character.

Note: If you change the S5 value, you must make corresponding changes in your data communications software.

S6 Wait Time for Dial Tone

Unit: 1 second

Range: 2–65 (North America), 4–255 (International), 4–7 (U.K.)

Default: 2 (North America), 4 (International and U.K.)

S6 defines the length of time the modem waits after ENTER is pressed before executing a dial command. The default setting is two seconds for North America, four seconds elsewhere.

S7 Time to Wait for Carrier

Unit: 1 second

Range: 1–255 (USA), 1–45 (Canada and International), or 1–55 (U.K.)

Default: 50 (North America and International) or 55 (U.K.)

S7 determines amount of time the modem waits for a carrier signal before it disconnects. The default value is 50 seconds except the UK model, which defaults to 55 seconds. This means that after dialing the modem waits for a carrier signal for up to 50 or 55 seconds and if none is detected terminates the call. The maximum S7 value is 255 seconds for the US model, 45 seconds for Canadian and International models, and 55 seconds for the UK model. S7 also determines the wait for silence time for the @ dial modifier.
