  • Channel monitor for connection to channel lines
    Patent number: 4477873
    Abstract: Apparatus for monitoring, in real time, the I/O channel activity between a computer and a locally attached device. The apparatus does not interfere with the operation of the I/O channel while monitoring its activity and records events and sequences of events as they occur on the channel. An operator selects the events and sequences of events to be recorded and detected conditions are stored in memory. In particular, the apparatus only detects selected signals having a period greater than a predetermined value. If this occurs, the channel Tag and Bus lines being monitored are recorded in memory.
