asynchronous
transmission
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.
AT command set 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.
AT prefix A prefix issued before every AT command (except
A/ and +++) which identifies the DTE’s data rate,
parity, and character length.
autobaud Modem automatically determines the
asynchronous DTE data rate when using AT
commands.
automatic answer A capability to respond to a call received over a
dial line.
baud A unit of signaling speed that is equal to the
number of symbols per second. This is not
necessarily the same as bits per second, although
the terms are frequently interchanged.
Bisync
Binary Synchronous Communications. An IBMr
communications protocol that has become an
industry standard. It uses a defined set of control
characters and control character sequences for
synchronized transmission of binary-coded data
between stations in a data communications
system.
bit A contraction of binary digit. A bit, which is the
smallest unit of information, represents a one or a
zero (sometimes called mark or space).
bps Bits per second. Indicates the speed at which bits
are transmitted across a data connection.
