AT Commands for CX930xx Modem Reference Manual
102752B Conexant 3-33
3.2.3 Call Control
D - Dial
This command directs the modem to go on-line, dial according to the string entered and
attempt to establish a connection. If no dial string is supplied, the modem will go on-line
and attempt the handshake in originate mode.
NOTE: If the ATD command is issued before the S1 register has cleared, the modem
will respond with the NO CARRIER result code.
If +FCLASS=0 is selected, the modem will behave as a data modem and will attempt to
connect to another data modem. The modem will have up to the period of time specified
by register S6 or S7 to wait for carrier and complete the handshake. If this time expires
before the modem can complete the handshake, the modem will go on-hook with the NO
CARRIER response. This command will be aborted in progress upon receipt of any DTE
character before completion of the handshake.
