INSYS GPRS 5.0 serial Functions
79
This setting will only apply to the operating mode TCP Listen. It is used to
communicate the just allocated IP address together with a unique device
ID to the server (IP address or domain name), when IP addresses are dy-
namically allocated.
6.10.1.3 Authentication for incoming TCP connection:
This setting will only apply to the operating mode TCP Listen. A TCP con-
nection is only accepted if the "caller" has sent a valid authentication via a
UDP packet in advance. This function is also used to terminate a "hanging"
TCP connection for the INSYS GPRS 5.0 serial (e.g. due to a network failure
or a crash of the remote terminal). When a valid UDP packet is received,
the existing TCP connection is terminated to be able to accept the new
connection.
