That's great news, David. I'm glad that you are having success using the new
CommExecuteFunction system call. I haven't had a chance to test it at all yet
personally but I was very confident that it would just work seeing as how
exposing it via the syscall mechanism uses these functions exactly the same as
how they are called by the user interface.

It would be great if we could pursuade LEGO to incorporate these changes since
they have no negative downside and a huge positive upside.

I think this would be a nice feature. I'll probably add it as a new function
id. Something like CONNECTBYNAME which would use the next available integer
value (which I don't recall off the top of my head).
I have been working on developing a unified code base which works with GCC and
IAR. I've got all the .txt files fixed so that the source compiles on GCC and
IAR but there are several other issues that I still need to sort out. Once I
get that completely working I will make my changes available publically. I'll
talk to Rasmus about putting the code on the sourceforge project he created.
