Mark,

I don't have much info on the card.   Attached is a ZIP file with some technical
info, including a code snippet, from Dan Boone at Applied Digital who I think
was involved in its development.   At the time I got it last year from him, it
wasn't of much help as it required a lower level of programming than I'm
able/willing to do.   Dan told me that an application communicated with the card
simply via a memory mapped I/O location at 280-282 (in fact when I installed the
card on Win98 machine, I had to reserved this memory range to make sure the card
could use it).  He said that there were no interrupt involved.   But, it seems
like Dan said something about being able to set jumpers to use an interrupt
(although this was not the recommended config).   Some time ago, I sent the info
below to David Huras who is the author of a CP290 shareware program X10WC that
I've used for sometime. At the time, I was wondering if David might be able to
add support for the IrDx card to X10WC as he's done with several other
controllers besides the CP290.    Turns out I wasn't ever able to get David a
card to use, but here's what he noted about the card from what I described to
him at the time:

"...if the card isn't interrupt driven, then this will require the software
developer to build polling routines to check for unprocessed data -- a little
more work for the developer (and the CPU)."

I'm not sure how ECS could deal with this.   Hopefully, the attached files might
give someone on the list some insight.  I'd didn't find them too useful and help
from the Applied Digital folks was pretty scarce.   I suspect that unless I'm a
programmer with software that I sell that I'm trying to make support their card,
they don't have time to bother.   They don't even have a website, so......

Anyway, thanks for the idea.   It hadn't occurred to me that perhaps ECS was a
possibility.

Here's the attachment:

P.S. a picture of the card can be found on Richard Wolf's (CD Jukebox) website
www.graywolfsoftware.com as this is one of the controllers that he supports via
the memory mapped I/O address (follow links from the main page to the Support
section and then Installation of Ir-X card).
