Cingular GPRS Raven User Guide Version 2.01 77
AT Commands
It is possible to communicate with the Raven across a TCP/IP network (using Cin-
gular’s network and the Internet). Telnet provides a terminal style connection to the
Raven. Note: Telnet is not a secure communications protocol.
Friends Mode can limit access to the Raven from the Carrier network and the Inter-
net. Friends Mode is a limited form of security.
