Destination
The Destination parameter either sets the phone number or gives the
name of the Station setting parameter that contains the phone number.
GSM-Dependent Configurations
The configuration for transmitting the reports over the GSM (or
cellular) network is basically the same as for PSTN, except that the
GSM option provides the possibility to transmit reports as short text
messages (SMS).
Transmission Mode
The Transmission mode parameter allows a selection between three
modes:
1. Data call: The report is automatically sent to the destination by
making a call. The report can also be polled, if the Poll command
is defined.
2. SMS message: The report is sent using the SMS message. The
report can also be polled, if the Poll command is defined.
3. Polled only: The report is only sent when polled by the remote
system.
Destination
The Destination parameter either sets the phone number or gives the
name of the Station setting parameter that contains the phone number.
NOTE The maximum length allowed for the SMS message is 160 characters.
Depending on the used modem, longer messages may be split into two
or more messages. SMS messages use 7-bit coding. The use of control
characters (<ASCII 32) may produce unpredictable results. For the
GSM 7-bit character set, see
Appendix B, GSM 7-Bit Character Set,
on page 377 .
