GPRS-IP Modem
A GSM modem with GPRS capability can be used to connect the QML
logger to the Internet, or directly to a private network through a
dedicated access point (APN). Also data call (CSD) can be used as an
IP carrier.
This modem control has been tested with Siemens MC35i GSM/GPRS
modem.
To include this component to setup, add the device Siemens GPRS-IP
and configure it as shown in
Figure 90 on page 209 . The only station-
specific parameter to configure is pin, the PIN code for the GPRS
modem.

Using Extended Characters with GPRS-IP Modem
In GSM-based communications, the GSM 7-bit character set is used
instead of the ASCII character set. Due to this, the character values for
extended characters are different from ASCII-based communications.
With the QML logger, extended characters based on the GSM character
set may be used in access point names, user names, passwords, and
reports to be sent over a GSM-based link. The GSM 7-bit character set
is presented in
Appendix B, GSM 7-Bit Character Set, on page 377 .
