Data Sheet
Flash hook switch for FHT (U4F) ms (default: 500 ms)
Pause before continuing for S8 seconds (default: 2
seconds)
Return to AT command mode
Wait for silence.
Polarity reversal detect. By placing the "G" character in
the dial string (i.e. ATDTG1), the modem will monitor the
telephone line for polarity reversals. If a busy tone is
detected, the modem will report "POLARITY
REVERSAL" if a polarity reversal was detected or "NO
POLARITY REVERSAL" if a polarity reversal was not
detected. In each case, the result code is followed by
"OK". If the S7 timeout occurs before a busy tone is
detected, the modem will report "NO CARRIER".
Polarity reversal monitoring begins after the last digit is
dialed and ends when the busy tone is detected or S7
timeout occurs.
Redial last number.
Pulse (rotary) dialing)
Tone (DTMF) dialing
Wait for dial tone before continuing for S14 seconds
(default: 12 seconds). Blind dialing modes X0, X1, and
X3 do not affect the W command. If the DOP bit (U7A,
bit 7) is set, the "ATDTW" command will cause the
modem to pause dialing and either report an "OK" if a
dial tone is detected or "NO DIALTONE" if a dial tone is
not detected.
