MALFUNCTION IN A MULTIPOINT ENVIRONMENT
In a multipoint environment, several terminals share the same communication line to a
computer. To avoid the garbling of data over this line, the computer assumes complete control
concerning which terminal may send information and which terminal may receive informa-
tion. However, if a power failure or some other disruption occurs and the communication line
comes down, you must take steps to ensure that your terminal is in a proper receiving state. In
particular, if the line goes down while your terminal is waiting for another terminal to send or
receive data, your terminal may continue to wait until the host computer sends an EDT.
