Detailed Description

Regression test for LCB LAT COmmunication boards.

Author:
Ed Bacho - ebacho@slac.stanford.edu

    These are the main subroutines for running LCB regression tests. They
    are intended to be run on VxWorks through the WindSh or across the
    network via LTX.
   
    The subroutines are structured to be used thru the WindSh rather than
    be called by other progs. They assume a single LCB board.
