    Steve,

    If you're running on NT, there's a nice Reftek program called NCI
    that allows you get the status of the Reftek (which includes GPS lock info)
    on command.  It also allows you to reconfigure the Reftek remotely.
    NCI actually interfaces to RTPD via disk files; RTPD passes the request
    to the DAS and then ships the reply back to NCI, again via disk files.
    I thought at one point that Reftek was going to make a Solaris version
    of NCI, but I don't know if that ever happened.

    If you're running RTPD with a reftek archive, the SOH info is written
    to the archive.  The directory structure of the archive is like:
    /archive/yeardoy/DASid#/stream/horriblefilename.  The SOH is written
    under stream=0.  horriblefilename is a mostly ascii file, so you can
    look at it with an editor.  It should include info about GPS locks.
    Er... this may only work on NT as well... I think the Reftek archive
    utilities are all Windows executables.

    I guess the only solution for Solaris users is to teach reftek2ew
    to request SOH packets from RTPD and to write their contents to
    the log file.  Or to bug Reftek for a Solaris NCI-like program.

    Lynn
