I would like to use Mach to control a serial io card I made.  However I can find very little about how to use the event driven serial control.  I did find a few posts about using fifo.  Is there somewhere that I can find more details?

I think the best thing to do is to look at the Plug In for the G100 and have a look at how the data is passed to it. THere is a Doc that Art did that tell how it works It is all on the downloads page.

Thanks
Brian
