error control
Various techniques that check the reliability of characters

flawed frames (ARQ).
facsimile
A method for transmitting the image on a page from one
point to another. Commonly referred to as fax.
fax mode
The mode used by a modem to send and receive data in
facsimile format. See definitions for V.17, V.27ter, V.29.

A mechanism that compensates for differences in the flow
of data into and out of a modem or other device. See
commands &Hn, &In, &Rn.
frame

header and trailer information attached. The added
information usually includes a frame number, block size
data, error-check codes, and Start/End indicators.
full duplex
Signals can flow in both directions at the same time over
one line. In microcomputer communications, may refer to
the suppression of the online local echo.
half duplex
Signals can flow in both directions, but only one way at a
time. In microcomputer communications, may refer to
activation of the online local echo, which causes the
modem to send a copy of the transmitted data to the
screen of the sending computer.
