Function
15:8
Reserved
Read returns zero.
Dial or pulse
0 = Normal ATDTW operation
7
DOP
1 = Use ATDTW for Pulse/Tone Dial Detection (see also ATDW command)
Adaptive Dialing
0 = Disable.
1 = Enable.
Attempt DTMF dial the fall back to pulse dial if unsuccessful. First digit is dialed as DTMF. If a
dialtone is still present after two seconds, the modem will redial as pulse.
6
ADD
If no dialtone detected after two seconds, the modem will continue to dial as DTMF.
5:3
Reserved
Read returns zero.
V.22bis Synchronous Mode*
0 = Normal ATDTW operation
2
V22HD
1 = Use ATDTW for Pulse/Tone Dial Detection (see also ATDW command)
Synchronous Mode*
0 = Normal asynchronous mode.
1
HDLC
1 = Transparent HDLC mode.
Fast Connect*
0 = Normal modem handshake timing per ITU/Bellcore standards.
0
FAST
1 = Fast connect modem handshake timing.
*Note: When V22HD, HDLC or FAST bits are set \N0 (wire mode) must be used.
