Set a second serial port for the counter. Use the 53131/53132 to
measure your UUT (1PPS) vs. the TBolt (1PPS). TBoltMon then
does sawtooth correction and logs the result. Rick's CNS TAC32
program does a similar thing. I think the 53132A is simply set to
talk only mode (does the CNT-90 do that too?) I'm not near my
lab now, or else I'd be more specific.

I figured that over the next few months the group will come up
with all sorts of additional information on our own.
