FILES IN THIS DIRECTORY:

DIGITAL.DU:	The driver file that gets sent to the E1405/E1406 VXI command
                module.

vxidldux:	VXI firmware download utility for use on HP-UX controller.
                This utility is provided to facilitate downloading the 
                DIGITAL.DU driver to an E1405/E1406 command module (typically
                across an HP-IB interface).

                "vxidldux" is documented in the manual page found in the
                directory /usr/hp75000/d20/man/vxidldux.1. To view this
                manual page using the "man" utility, change your "MANPATH"
                environment variable to include this directory:
                  eg:
                       MANPATH=$MANPATH:/usr/hp75000/man; export MANPATH
                and then entering,
                       man vxidldux
                Also, you may query vxidldux for options by entering,
                       vxidldux -?

                "vxidldux" uses the SICL (PIL) kernal driver to communicate
                to the instrument, and thus, requires that the user first
                install the PIL device drivers. See the E1496 software 
                installation guide to perform this task.

                A typical use of the vxidldux utility to download the
                DIGITAL.DU Model D20 driver into an E1405/E1406 command module 
                follows (into dram);

                                      == WARNING ==
                      The following 2 commands will clear existing 
                      drivers from the VXI command module prior to
                      downloading the D20 driver (from the respective
                      memory being loaded). If you wish to load several
                      drivers, then add the other driver file names 
                      to the end of the command parameters.

    Loading D20 firmware into volatile RAM (if E1406, load/run switch set to
    the "Run" position). Note that drivers loaded in this manner will be
    erased when the next "DIAG:BOOT:COLD" command is executed on the VXI command
    module):

        vxidldux -a 9 -e 0 -d hpib -c"diag:dram:cre 0;:diag:boot" DIGITAL.DU
 
 
    Loading D20 firmware into flash RAM (on E1406 only with Load/Run switch set
    to "Load" position):

        vxidldux -a 9 -e 0 -d hpib -c"diag:fram:cre 0" DIGITAL.DU

  
                See the vxidldux manual page for details and for defaults used.
