6.5.6 Status commands
Page 38 of 63
Events and error messages are recorded in an "operation status word" in
the ZDUE-GPRS-PLUS-VI. This is stored in volatile RAM, and is thus lost in
the event of a power failure. The status word can be read from the device in
order to determine the current operating status.

Additional status information that can be read from the ZDUE:
GSM field strength
GSM network operator ID (e.g. 26201 for T-Mobile)
GSM location area ID
GSM cell ID
IMEI (International Mobile station Equipment Identity): Serial number
of the GSM module
IMSI (International Mobile Subscriber Identity): ID number of the SIM
card
These value are queried from the ZDUE-GPRS-PLUS-VI via service
command (see 6.5.7).
The ZDUE-GPRS-PLUS-VI enables the reading and resetting of the status
word. During reading the highest-value bit is transmitted first; each bit is
represented by an ASCII character '0' or '1'.
