| Description |
describes communications in a single direction at a time.
One side sends and the other side receives. When the roles reverse; the sending side now receives and the receiving side now sends. On "ASCII" terminals used with the Pick system, "half duplex" is the mode in which characters entered from a keyboard are displayed on the terminal screen and simultaneously transmitted to the Pick host. Normally, Pick ports are configured for "full duplex" also called "echo-plex". Every character received is "echoed" to the terminal. The system expects the terminal to also be in "full duplex". If a terminal is inadvertently set to "half duplex", each character is displayed twice for each keystroke. |
