| Description |
simulataneous bidirectional communications. Both sides send and receive with virtually no turnaround time.
On "ASCII" terminals used with the Pick System, "full duplex" is the mode in which characters entered from a keyboard are transmitted to the Pick host but not displayed to the screen. Normally, Pick ports are configured for "full duplex" also called "echo-plex". Every character received is "echoed" to the terminal. Upon a keystroke, the character viewed on the screen has made a round trip from the system and back to the screen.
