SMS processing through the application
The device will not delete unknown SMS messages if in the HSComm software in the tab
"Basic settings" in the group "GSM connection" the check box "Leave remote SMS in SIM
buffer" is marked. End device applications can therefore use these SMS messages. (Oper-
ating mode AT**SMSRX=2),
The SMS which are not processed by device stay in the buffer of the SIM card until they
are retrieved by the application via the serial interface, and deleted.

plication is queried (= activity at the RS232 interface).

Note
If the query cycle is triggered frequently, for example due to activity
at the RS232 interface, this may result in the device being no longer
able to start a query of the SMS input buffer.
