COMMAND Description
Operation
Support
$QCCLR clear mobile error log Clears the mobile error log Supported
$QCDMG
transition to diagnostics
monitor operation
Returns OK and then transitions the
mobile’s serial port to DM mode; DM
mode runs at rate set by $QCDMR
command and uses a proprietary
halfduplex protocol; default DM rate
fixed at 115200 bps
Supported
$QCDMR=
<rate>
set DM baud rate
Changes DM rate that will be used on
mobile’s serial port when mobile’s
serial port transitions to DM mode; DM
mode is entered after $QCDMG
command is issued; default DM rate is
fixed at 115200 bps; test command,
i.e., $QCDMR=?, returns rates
supported and query command, i.e.,
$QCDMR?, returns current
Rate
Supported
&V
dump configuration

then back on) the Rm port Carrier
Detect pin when Data calls end
Supported
$QCTER=
<rate>
Set TE-DCE baud rate
Baud rates supported
are identical to +IPR
command.
Sets TE-DCE rate at which DCE will
accept commands; this data rate also
becomes the default and is stored in
NV RAM, changing the +IPR
command default rate; test command,
i.e., $QCTER=?, returns rates
supported and query command, i.e.,
$QCTER?, returns rate last issued by
$QCTER command or default rate
Supported

Sets the default primary IP address
used for Domain Name Services;
used only if no DNS server address is
received over the air during PDP
context activation; value is stored in
NVRAM.

$QCDNSS=
<address>
Set secondary DNS IP
