Not reliably.  The only way to check that I know of is to squirt a
signal into the cable and see if you get a reflection off the end.  This
needs rather specialised equipment.  The only software way of doing it
that I can think of would have to rely on detecting error rates or
something - a high error rate would imply poor termination.

Ah...  Sorry, I'm useless.
