Dial or Pulse.
0 = Normal ATDTW operation
1 = Use ATDTW for Pulse/Tone Dial Detection (see also ATDW command)
Adaptive Dialing
1 = Enable
0 = Disable
Attempt DTMF dial, then fall back to pulse dialing if unsuccessful. First digit is dialed as
DTMF. If a dialtone is still present after two seconds, the Si2457/34/15/04 will redial the first
digit and remaining digits as pulse. If a dialtone is not present after two seconds, the Si2457/
34/15/04 will dial the remaining digits as DTMF.
V.22bis Synchronous Mode.*
0 = Normal asynchronous mode.
1 = Transparent HDLC mode.
Synchronous Mode.*
0 = Normal asynchronous mode.
1 = Transparent HDLC mode.
Fast Connect.*
0 = Normal modem handshake timing per ITU/Bellcore standards.
1 = Fast connect modem handshake timing.
