Glossary 78
protocol: A set of rules and conventions that makes it possible to transfer
information between computers. If you’re transmitting a file, both
modems must use the same protocol—just as two people talking on
the telephone must speak the same language to communicate
effectively. Examples of modem protocols are V.34, V.42, and V.90.
Public line: A line served by a telephone company to be connected to an
opposite station via the exchange.
Pulse dialing: A dialing method that uses pulses instead of tones to
generate a telephone number. Generally associated with rotary dial
phones, although some push-button phones can be used on pulse
lines.
R Reliable mode: Reliable mode is for error-free communication by MNP
or V.42.
Result code: This code returns to the computer the results of executing a
command sent from it to the internal modem in characters or
numeric values.
RJ11: A modular telephone connector used on most telephone networks
and direct-connect modems.
RTS signal: A Request to Send signal is an RS-232C standard that
indicates the modem is ready to receive data.
RS-232-C: The standard defining control, data and status signals for
cables allowing asynchronous communication with computers,
printers, and other peripheral devices.
S serial: The handling of data bits one after the other.
serial communications: A communications technique that uses as few as
two interconnecting wires to send bits one after another.
serial interface: An interface between systems or system components in
which information is transmitted sequentially, one bit at a time. The
transmitted bits are reassembled at the receiving component. A
modem uses a serial interface.
serial port: A communications port (COM1 or COM2) to which you can
connect a serial device, such as a modem, a mouse or a serial printer.
stop bit: In asynchronous serial communications, one or more bits
indicating the end of a block of characters.
