I'm resurrecting my SCSI target stuff from 386bsd. If processor A tries to read 32 bytes from processor B, and processor B only sends 8, physio keeps looping on the read until we either timeout or receive the full 32 bytes (four transfers). What is the right way to handle this? My inclination is that we want to return a short read, but then I can't just use rawread and rawwrite. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
