/Kn PROPRIETARY COMMAND | |
Command |
Protocol |
\K0 |
(1) Break signal from DTE, normal/MNP mode: modem does not send break signal to the remote modem and enters the command mode. (2) Break signal from remote modem, normal mode: modem clears terminal and modem buffers, then returns break signal. (3) Break signal from DTE, direct mode: modem sends a break to the remote modem, then enters the command mode. |
\K1 |
(1) Break signal from DTE, normal/MNP mode: modem clears terminal and modem buffers, then sends a break signal to the remote modem. (2) Break signal from remote modem, normal mode: modem clears terminal and modem buffers, then returns break signal. (3) Break signal from DTE, direct mode: modem sends a break to the remote modem, then enters the command mode. |
\K2 |
(1) Break signal from DTE, normal/MNP mode: modem does not send break signal to the remote modem and enters the command mode. (2) Break signal from remote modem, normal mode: modem does not clear buffers and returns a break signal (3) Break signal from DTE, direct mode: modem sends a break signal to the remote modem. |
\K3 |
(1) Break signal from DTE, normal/MNP mode: modem does not clear buffers and sends a break signal to the remote modem. (2) Break signal from remote modem, normal mode: modem does not clear buffers and returns a break signal (3) Break signal from DTE, direct mode: modem sends a break to the remote modem, then enters the command mode. |
\K4 |
(1) Break signal from DTE, normal/MNP mode: modem does not send break signal to the remote modem and enters the command mode.
