$QCDMG

Transitions to

Diagnostics

Monitor (DM)

operation

Returns OK and then transitions

the mobile’s serial port to DM

mode; DM mode runs at the rate

set by $QCDMR command and

uses a proprietary half-duplex

protocol. The default DM rate is

fixed at 115200 bps.

$QCDMR=

<rate>

Sets DM baud

rate

Changes the DM rate that will be

used on the mobile’s serial port

when the mobile’s serial port

transitions to DM mode; DM

mode is entered after $QCDMG

command is issued. The default

DM rate is fixed at 115200 bps.

Test command, i.e.,

$QCDMR=?, returns rates

supported, and the query

command, i.e., $QCDMR?,

returns the current rate.

are identical to

+IPR command

Sets the 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 the rates

supported and query command,

i.e., $QCTER?, returns the rate

last issued by the $QCTER

command or the default rate.
