Aha,

That's actually quite interesting. So I guess the likelihood is that
trying to get a "press and hold to dim cycle" going this way
would
probably result in the X10 light first either switching OFF or ON to
100% initially, and then proceeding to dim up or down to the requested
level... - which isn't that far off how some X10 modules dim natively
anyway!

Would it be feasible to code around this in Comfort perhaps?...

I'm thinking along the lines of...

If counterXX changes
Wait 4 seconds
Read value of CounterXX
Send X10 preset dim to required address with value of counterXX
End if

Of course this is only postulated purely as an academic curiosity... -
the reality of building a 4 second delay into a lighting dim response
sounds like an appalling idea!!
