Hi Donald,

when I hooked up the scope the additional loading was already too much
to stop the thing from working,

Either you really screwed up your connecting the scope, or this is not
RS-232.

Do as Donald suggests, that is a valid, and easy thing to do. If it
doesn't work because the second monitoring port loads the device too
much, then it is not RS-232.

so probably it
wouldn't work with an extra port either, therefore I didn't even try.
This is the first DMM I've seen that runs at such a high speed, I
thought the 50 us were glitches as well, because the signal looks very
bad, already the 104 us (now I know two bits...) are barely defined.
