Reset Queue (0x0025)

parameter0

parameter1

bufferLength

Remarks

This function is particularly geared toward tape applications, because they need tighter control on how sequential requests are executed.

When the CDM gets this message, it must translate it into either a hacbType = 0 or priority HACB request. Otherwise, if the device queue (which is controlled by the HAM) is currently frozen, the unfreeze request remains in the queue and is never executed.
