is avaible after power-off and any happened alarm. Therefore for
consecutive alarm settings input <text> again is not necessary and
should be avoided due to limited no. of flash memory write cycles
(e.g. 100.000).
<tlength> integer type value indicating the maximum length of <text>. The
maximum length is 16.
Unsolicited result code
As indication of an alarm event output is:
+CALA: <text>
Reference
GSM 07.07
Note
<text> should not contain characters which are coded differently in ASCII and
GSM (e.g. Ä, Ö, Ü), see also „Supported character sets“, pg. 10 and “Alphabet
tables”, pg. 144.
Please consider when using multiplex mode (+CMUX, pg. 67):
1. It is possible to use +CALA with every logical channel (1 – 3).
2. The total no. of possible alarm events is shared by all channels. If <n> = 0 is
returned by the test command, this indicates that only one common alarm
time is possible for all logical channels.
3. For every channel a different <text> parameter can be stored.
4. <text> will be output on the same logical channel the alarm was entered. If
not in multiplex mode, <text> will be output independent of the related
channel.
5. The read command returns all pending alarms, independent on which logical
channel an alarm was entered. It´s up to the user to identify these alarms by
specific <text>s.
