The GPIB-SCSI-A records this error if the GPIB-SCSI-A
is performing a high-level SCSI operation and the
selected Target enters an unexpected phase that the
GPIB-SCSI-A is not prepared to handle. If this occurs,
you must use the low-level function calls to perform the
desired command.

The GPIB-SCSI-A records this error if the Target that is
communicating with the GPIB-SCSI-A unexpectedly
releases the SCSI BSY* signal without either notifying
the GPIB-SCSI-A of its intention to disconnect or
finishing the command normally by going through the
Status and Message In phases.
EPAR
S/G 6
The GPIB-SCSI-A records this error if it is configured to
detect and report SCSI parity errors and the
GPIB-SCSI-A detects a parity error on any read of data
from the SCSI bus. This is configurable with Switch 7 of
configuration switch SW2.

128-135 (80-87 hex)
The GPIB-SCSI-A records this error if it is configured
for automatic testing (by the
autotst
command), and
the GPIB-SCSI-A detects an error on a Test Unit Ready
command issued to one of the specified SCSI Target IDs.
The lowest three bits of this error code indicate which
SCSI Target ID had the error. In order to determine the
exact error that occurred, you can issue the
tstur
command to the SCSI Target ID indicated by the lowest
three bits.
