READ BUFFER COMMAND (3Ch)
The READ BUFFER command is used in conjunction with WRITE BUFFER as a
diagnostic function for testing the drive’s data buffer for possible diagnostic data
and for checking the integrity of the SCSI bus. In addition, by using buffers 1
and 2, the READ BUFFER command allows the contents of the tape system’s
local RAM/EEPROM, and DRAM to be transferred over the SCSI bus. Buffers 1
and 2 provide a diagnostic capability for the system’s firmware.
