iR1200 Modem
43
The two best-know Internet protocols, often erroneously thought of as one protocol. TCP
enables two hosts to establish a connection and exchange streams of data. TCP
guarantees delivery of data and guarantees that packets will be delivered in the same
order in which they were sent. IP acts as a postal system, allowing you to address a
package and drop it in the system, but doesn’t provide a direct link between you and the
recipient. TCP/IP, on the other hand, establishes a connection between two hosts so that
they can send messages back and forth for a period of time.
Terminal Mode
The mode that accepts AT commands. Also known as Command Mode. When your
modem is in this mode, it is waiting to receive AT commands that you type from your
communication software.
Transmission Rate
The rate at which data is transferred measured in bits per second. Common transfer rates
are 9.6bps / 19200bps / 57600bps / 115200bps
Wireless Data Services
One of the functions of your Internet-ready phone. Wireless Data Services uses both
circuit-switched and packet data transmission.
