asynchronous transmission

[ā′siŋ·krə·nəs ‚tranz′mish·ən]
(communications)
Data transmission in which each character contains its own start and stop pulses and there is no control over the time between characters.

asynchronous transmission

The transmission of data in which each character is a self-contained unit with its own start and stop bits. Intervals between characters may be uneven. It is the common method of transmission between a computer and an analog modem, although the modem may switch to synchronous transmission to communicate with the other modem. Also called "start/stop transmission." Contrast with synchronous transmission.

Both synchronous and asynchronous transmissions are supported, including such technologies as Voice over IP (VoIP) and IP multicast.
Asynchronous transmissions, at speeds from 50 bits per second (b/s) to 19.2 kb/s, are accomplished by connecting the RS-3232-C port on a student's computing device, for example, to an ITE-type (for Integrated Terminal Equipment) telephone.
Some local data sets provide such features as full and half-duplex operation, diagnostics and self-tests, synchronous and asynchronous transmissions, and controlled or continuous carrier operation.
