Remote echo

Network hardware; Modems

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.

Serial transmission

Network hardware; Modems

The consecutive flow of data in a single channel. Compare to parallel transmissions where data flows simultaneously in multiple channels.

Start/stop bits

Network hardware; Modems

The signalling bits attached to a character before and after the character is transmitted during asynchronous transmission.

Terminal

Network hardware; Modems

A device whose keyboard and display are used for sending and receiving data over a communications link. Differs from a microcomputer or a mainframe in that it has little or no internal processing ...

Terminal mode

Network hardware; Modems

Software mode that allows direct communication with the modem. Also known as command mode.

Throughput

Network hardware; Modems

The amount of actual user data transmitted per second without the overhead of protocol information such as start/stop bits or frame headers and trailers. Compare with characters per second.

USB transfers isochronous or asynchronous data and is used to replace the cable "clutter". USB is designed as "plug and play." This means devices such as modems are automatically detected once they ...
