Glossary
A configuration area containing configuration options currently in use by the modem.
When a power cycle occurs, a reset is performed, or a save is issued, this area is updated
with the contents of Active (Saved).
A nonvolatile configuration area containing the most recently saved configuration
options. Any changes made to configuration options can be saved by issuing an
AT&W0 command.
Test in which the modem's transmit VF signal is looped to its receiver.
A type of signal composed of continuously variable values, used to transmit voice or
data over telephone lines.
The state of a modem that it is ready to receive an incoming call. For example, an ATA
(Answer) command has been issued to place the modem into online answer mode. The
modem has been forced off-hook and is generating an answer tone, beginning the
handshaking process with the calling modem.
This code (American Standard Code for Information Interchange) is a 7-bit code which
establishes compatibility between data services. ASCII is the standard for data
transmission over telephone lines. The ASCII code consists of 32 control characters
(nondisplayed) and 96 displayed characters.
In V.34, the ability of a device to transmit at a different rate than it receives.
A factory preset configuration area containing the configuration options most often used
in asynchronous dial networks.
A data transmission that is synchronized by a transmission start bit at the beginning of a
character (five to eight bits) and one or more stop bits at the end.
A group of commands, issued from an asynchronous DTE, that allow control of the
modem while in Command mode. All commands must begin with the characters AT and
end with a carriage return.
A prefix issued before every AT command (except A/ and +++) which identifies the
DTE's data rate, parity, and character length.
To automatically determine the asynchronous DTE data rate.
