4.4 AT%D Automatic Dial on DTR Line Activation
Syntax
Command Description
Enable and disable automatic dialling on DTR line activation.
A more generic way to control the TC35i via its DTR line is available with
AT^SCFG
, refer to parameter <AutoEx-
ecATC>
.
If automatic dialling is enabled with
AT%D and the DTR line switches from OFF to ON state, the ME attempts to
set up an outgoing call to the number stored at the first index of the ''ME'' phone book, or using telephone number
"112" in case of an emergency call.
If enabled, DTR activation triggers a dial command (
ATD) as though it were entered by a TE. Therefore if in this
situation characters are entered on the same serial channel the ongoing dial command will be terminated (user
break).
When a call setup starts all other active or held calls are dismissed.
Repeated DTR activation events are ignored while call setup is in progress or during a call established by DTR
activation. Also all DTR activation events during multiplex mode are discarded.
