Abstract:
In an information handling system in which data transmitted to a remote receiver is held for retransmission in the event of a transmission error, the system having an input/output (I/O) buffer, a method of selectively using the I/O buffer as a retransmission vehicle for retransmitting the data in the event of a transmission error, the method comprising the steps of:determining whether the I/O buffer should be used as a retransmission vehicle for transmitted data; if it is determined that the I/O buffer should be used as a retransmission vehicle for the transmitted data, holding the data in the I/O buffer for retransmission to the receiver until an acknowledgment is returned by the receiver; and if it is determined that the I/O buffer should not be used as a retransmission vehicle for the transmitted data, holding the data in a buffer other than the I/O buffer for retransmission to the receiver until an acknowledgment is returned by the receiver.
