Telenetics V.32bis Series, V.34-SDC Register 5-Backspace Character, Register 6-Wait for Dial Tone

AT ACU

Using the

S-Register 5—Backspace Character

Stored in Nonvolatile Memory?:	No
Status-Only?:	No
Default Setting:	8
Range:	0 to 127

This S-Register determines the decimal value of the backspace character. The default setting, 08, translates to the ASCII <BS> (backspace) character. Values greater than 32 (except 127) disable the backspace function.

S-Register 6—Wait for Dial Tone

Stored in Nonvolatile Memory?:	Yes
Status-Only?:	No
Default Setting:	2
Range:	1 to 255 (seconds)

If Call Progress is set to 0, 1, or 3 (ATX0, ATX1, ATX3), and blind dial is selected, the modem does not look for a dial tone. Instead, the modem goes off-hook and waits for the number of seconds specified by S-Register 6 before blind dialing a telephone number (if Blind Dial is set to S6, AT*BD2). This S-Register does not affect the wait dial modifiers W, w, or :.

S-Register 7—Wait for Data Carrier

Stored in Nonvolatile Memory?:	Yes
Status-Only?:	No
Default Setting:	30
Range:	1 to 255 (seconds)

If Call Timeout (AT*TT) is set to S7, the value of S-Register 7 determines the number of seconds that the modem waits for a carrier signal from the remote modem after dialing or answering a call.

S-Register 7 also affects the dial modifiers @, W, w, and :.

Dial Modifier “@”

If Call Timeout (AT*TT) is set to S7, the value of S-Register 7 determines the length of time for which the @ dial modifier instructs the modem to detect five seconds of silence.

Dial Modifier “W”, “w”, and “:”

If the Dial Wait option (AT*DD) is set to S7, the value of S-Register 7 determines the value of the dial wait modifier. The dial wait modifier determines how long the modem waits for a second dial tone after the modem has dialed a number.
