摘要：The I/O configuration of a computer system includes two channels (A, B) whichare capable of being available on up to four interface ports (P0 - P3), with the ports beingincorporated within the channel in order to eliminate the need for an external switch.Control means are provided for monitoring the status of each channel and each port inorder to achieve expeditious transfers through a selected port between the channel andperipheral devices. Error reporting is limited to the area directly affected by the error,and immediate disconnection helps to isolate the error and allow time for erro recoverybefore the particular channel (A or B) or port again becomes available.
