|(communications)||remote echo - (Obsolete: "full-duplex") A mode of operation
of communicating programs or devices in which the sending
system does not display the characters the user enters, but
only sends them to the remote system which then "echoes" them
back to be displayed to the user. This lets the operator see
not only typing errors, but also transmission errors. This is
now the usual mode of most systems with remote users.|
Contrast: local echo.
