Description
Instructs the modem (DCE) to set all parameters to their
QUALCOMM-defined defaults. This command performs the
same operation independent of whether or not <value> is
specified. QUALCOMM-defined defaults are the default
values for each AT command specified in this chapter .
This command sets the modem baud rate to its
power-on/reset default value (see Set Rm Interface Command
Baud Rate (+IPR) on page 6-38), but does not reset the
$QCMODE value to its power-on/reset value. (Compare the
behavior of the Z command, Reset to Default Configuration (Z)
on page 6-15.)
If the modem is in Online-Command mode, the data call is
released and the modem returns to Command mode.
