Local Echo (Keyboard Send-Receive)
This mode selects local echo, which causes every character transmitted by the terminal to automatically appear on the screen. Therefore, the computer does not have to transmit (echo) the character back to the terminal for display. When local echo is off, the terminal only transmits characters to the computer. The computer must echo the characters back to the terminal for display. Select send-receive mode by using the following sequences.
