- Full Duplex != Local Echo ON (Local Echo ON is Half-Duplex)
- Full Duplex == Local Echo OFF
-
- This an overly simplistic answer. Local echo is designed to deal with hosts
- that DO NOT echo back the characters typed at the terminal. With local echo
- on, and a host that does echo, each character that you type will be displayed
- twice (i.e. type 'A', you see 'AA' on the screen). Duplexing (Full or Half)
- determines whether the transmit and receive channel can be used simultaneously.
- Full duplex means both transmit and receive can be active at the same time.
- This is a hold-over from MODEMs of 10 years ago and older. In order to
- get reasonable data rates (i.e. >300bps) over standard telephone lines,
- MODEMs used the entire bandwidth of the channel for transmission. This meant
- that only ONE transmitter at a time could be active (and multiple receivers
- could listen in - networking using MODEMs).
