Yes, trying to make a living is keeping me away from my hobbies for
unacceptable periods. I guess we all have the same problem to a more or
lesser degree.

Ah, that explains a lot. I was expecting an answer along these lines.

You will definately be doing us all a big favour. The only reason why I was
trying to use this card is to save my onboard port from damage in the event
of me doing something stupid (not impossible at all). I do however
understand your problem with available time and priorities.

I will do this tomorrow and report back. Am I correct in assuming that if
the port is found at a specific address, all I need to do is check that this
address is specified in the .ini file? If I can then still not get out of
e-stop I will have to check the other settings in my .ini file more
carefully.

Thank you for replying.
