I'm sorry; I should have been more
specific. Let's take a very simple case:
I->T READ 1 block
T->I Unit Attention (06/29/01)
(or BUSY, etc)
Since all of the data was not returned, should
the U bit be set? Section 10.4.1 does not specify.
bit 6 - (U) set for Residual Underflow. In this case, the
Residual
Count indicates the number of bytes that were not
transferred out of the number of bytes that were expected to
be transferred. For a bidirectional operation, the Residual
Count
contains the residual for the write operation.

For some devices and settings the underrun may the
cause of the check condition so it certainly should be set whenever
appropriate.

Should the target set the U bit when it gives a check condition to a
data-in command?
