retransmits the data to printer, the printer is said to echo the CRT.
erase: See delete.
escape: 1) A code (ASCII code 27), signalling the computer that what
follows are commands; used with peripheral devices such as
printers and modems. 2) A means of aborting the task currently in

escape guard time: A time before and after an escape code is sent to
the modem which distinguishes between escapes that are part of
the transmitted data, and escapes that are intended as a
command to the modem.
