/Kn PROPRIETARY COMMAND | |
Note: | Selects the modem response when a break signal is detected from the DTE or remote modem. |
Command | Protocol |
í \K5 | (1) Break signal from DTE, normal/MNP mode: modem sends a break signal to the remote modem in sequence with transmitted data. (2) Break signal from remote modem, normal mode: modem returns break signal in sequence with buffered data. (3) Break signal from DTE, direct mode: modem sends a break signal to the remote modem. |
/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. (2) Break signal from remote modem, normal mode: modem returns break signal in sequence with buffered data. (3) Break signal from DTE, direct mode: modem sends a break signal to the remote modem. |
