OTUHFLG - Integral OTUs historic fault flags
The Integral OTUs Historic Fault Log Flags - see OTU documentation.
Normal examination of the OTU's fault logs should be made using the OTU
commands 'GLF' and 'GLD' rather than these engineering commands.
Note: This command can still be entered even if no Integral OTU is fitted or one
is connected but has failed but will obviously not return the correct values.
