DTCERT - A program to certify DECtapes on-line.
DTCERT will generate and write the timing marks on a DECtape. Data is then
writen on the tape and verified. All blocks are then zeroed and the directory
block is initialized. All this is done without disrupting normal timesharing.
DTCERT requires a 500 or 600 series monitor running on a KA, KI or KL to be
configured with real time trapping enabled, one real time device and a free
PI channel. When certifying DECtapes, DTCERT must have all the DECtape
drives on the controller. DTCERT requires RATTRP and LOCK privilages to run.
