parity
A simple error-detection method that
checks the validity of a transmitted
character. Character checking has been
surpassed by more reliable and efficient
forms of error checking, including V.42 and
MNP 2-4 protocols. Either the same type
of parity must be used by two
communicating computers, or both may
omit parity.
protocol
A system of rules and procedures governing
communications between two or more
devices. Protocols vary, but communicating
devices must follow the same protocol in
order to exchange data. The format of the
data, readiness to receive or send, error
detection and error correction are some of
e operations that may be defined in
protocols.
RAM
Random Access Memory is memory that is
available for use when the modem is turned
on, but that clears of all information when
the power is turned off. The modem's RAM
holds the current operational settings, a
flow control buffer, and a command
buffer.
remote digital loopback
A test that checks the phone link and a
remote modem's transmitter and receiver.
remote echo
A copy of the data received by the remote
system, returned to the sending system, and
displayed on the screen. Remote echoing is
a function of the remote system.
