4 0-7 The Routine in Error field contains the Routine ID of the failing routine. If this
field contains 00h, no errors were detected during the last execution of a SEND
DIAGNOSTIC command.
5 0-7 The Execute Count field contains the number of passes attempted before an error

Routine 50, and a pass count of 7 for Routine 51, and an error was detected on
the third attempt to execute Routine 51, this field would contain a 3.
