MacTest Pro: False SCC Loopback Error On Power Macintosh (7/94)


When running MacTest Pro for the Power Macintosh, I am consistently getting "SCC loopback data count error" when running the serial loopback test. All other tests pass on the computer. Is this a known issue on the diagnostics?

The diagnostic group was able to confirm that this is a bug in Comm Ports test v1.1 which will be fixed in version 1.2 of the test. Version 1.2 is expected to ship sometime in August assuming no delays.

If there are no other symptoms which would normally point to a serial port failure, this error can be ignored.
