TCP Transparent
This function represents the main characteristic of the extended function. By means of
the integrated TCP/IP stacks, the INSYS GPRS 5.0 serial functions as “modem emulation”
for the application; the user data are provided transparently via the serial interface ("TCP
transparent" connection).
There is no need for the application to process any additional protocol stacks.
Due to the fact that the IP address of the the INSYS GPRS 5.0 serial can not be accessed;
only outgoing TCP/IP connections are supported.

transparent” connection, i.e. after the end/termination of the “TCP transparent”
connection follows the calculation of the GPRS provider, where the data accumu-
lated until then is rounded to the next billing unit.
