ABSTRACT:
A method and arrangement for shutting off a receive channel in a data communications system to prevent accidental or intentional overwhelming of the memory of the system such as that caused by a continuous burst of short frame data. The data frames received are monitored by a shutoff counter as they are received on one of the channels of a serial input/output (I/O) device. When the shutoff count is reached, the receive channel will be shut off. The current value of the shutoff counter is compared to a value stored in a warning register. Before reaching the shutoff count, a warning is generated when the current shutoff counter value reaches the warning register value.
