Macro Action Description
Example: $PPassword&C3&N&M$ means prompting a Password pop-up
box, the maximum number of input characters is 3, the input type is Number,
and the input is masked by the asterisk characters “*” (dot for
T57W/T48U/T48S/T48G).
Note: &T<title> is not applicable to
T57W/T48U/T48S/T48G/T46G/T42G/T41P/T29G phones.
$P<EDK user input prompt
X>N<characters number
allowed>$
The user input prompt string.
“EDK user input prompt X” means which EDK user input prompt is invoked. It
indicates the X defined by “edk.edkprompt.X.enable”.
“characters number allowed” defines the maximum number of input char-
acters. You need to press the Enter soft key to complete data entry.
Example: $P2N5$ means invoking the EDK user input prompt 2 and inputting
5 characters at most.
Note: For more information on EDK user input prompt, refer to EDK User Input
Prompt Configuration.
$L<label>$
This is the label for the entire operation. The value can be any string including
the null string (in this case, no label displays).
This label is used if no label is configured for a custom DSS key or soft key,
otherwise, this one is ignored. Make this the first entry in the action string.
Example: $LEDK2$1234$Tinvite$ defines calling out the number 1234 and
using the label “EDK2” for a Custom Key.
$LED<color and time>&L<label>$
(not applicable to T19(P) E2/CP920
phones)
The status of the BLF/BLF list DSS key LED. Specify the LED color for the
BLF/BLF list DSS key and the duration time (in milliseconds) for the cor-
responding status of the BLF/BLF list DSS key. The valid value of the duration
ranges from 100 to 60000ms.
Can be composed of multiple combinations of “color” and “time”. The status
will be stuck in an infinite loop until triggered by other macros.
Supported colors include (must be lowercase):
l r (red)
l ri (red; red with an incoming mark for T57W/T48U/T48S/T48G)
l ro (red; red with an outgoing mark for T57W/T48U/T48S/T48G)
l rd (red; red with a DND mark for T57W/T48U/T48S)
l g (green)
l gi (green; green with an incoming mark for T57W/T48U/T48S/T48G)
l go (green; green with an outgoing mark for T57W/T48U/T48S/T48G)
l y (yellow)
l yi (yellow; yellow with an incoming mark for T57W/T48U/T48S/T48G)
l yo (yellow; yellow with outgoing mark for T57W/T48U/T48S/T48G)
l yd (yellow; yellow with a DND mark for T57W/T48U/T48S)
l o (off)
&L<label> (Optional.): You have to put the “&L<label>” last in the command
flow.
Example: $LEDg1000o100r300&Lidle$ means an infinite loop for BLF/BLF
list DSS key LED status: glow green for 1000ms, be in the off state for 100ms
and then glow red for 300ms. At the same time, the label of the BLF/BLF list
DSS key is changed to “idle”.
