* From the T10 (formerly SCSI) Reflector (t10 at, posted by:
* John Lohmeyer <lohmeyer at>
T10 is planning to remove all documentation on High-Voltage Differential
drivers and receivers from the SPI-3 draft standard.  This does not include
documentation on the DIFFSENS voltage levels for HVD.

This does not mean that you cannot continue using HVD as documented in
SPI-2.  It just means that T10 will not continue to document HVD in newer

If you object to this proposal, please respond to this reflector
(t10 at or directly to me (lohmeyer at by July 9, 1998.
