I used to have a couple Radio Shack DVOMs that had a serial port.  A few
times I left one in the field hooked to a laptop with a terminal program
running and recorded data for 24hrs to PROVE that the customer had
shitty power and that the problem was not system.  (Whatever system it
was.)

For some reason ODC59A seems to come to mind.  That might have been the
part number.  Of course Radio Shack still survives in the form of a
couple of independent stores that have a stingy selection of nothing
(two stores I know of), but that is the last twitching of a dead corpse
with a little residual energy reacting to outside stimulus.  Even before
the death throes they hadn't had real Radio Shack stuff for years.

I think it was Jim who actually helped me find the part number when my
first one died and I was looking for another one.
