Hi Scott,

The layering will pass through these procedures:

IOChan.mod:RawRead
RTgen.mod:doReadLocs
RTfio.mod:dorbytes

sometimes I find it easier to use gdb to single step though the
calling of these layers once one knows the a position in the
application where everything is okay and another when the read has
failed.
