S-Register 5—Backspace Character
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
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
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.
