X: Send a Priority Forced Message 
Expanded Function X is a message that enables you to send a priority forced message. 
A  priority forced message is a group of text characters in the receive buffer that is immediately 
displayed even if the DOS terminal is in the compose mode. 
Reset Key Sequence - ALT-R 
The DOS terminal operator presses the [Alt] [R] key sequence to reset the DOS terminal. This 
will toggle between the priority forced message in the receive buffer and the compose buffer. 
Application 
You can use Expanded Function X to alert the DOS terminal operators about the system going 
down.
