Yes - they don't seem to be switched on by default. I decided that if I'm
going to have to implement ring buffers to handle the FIFOs I might
as well go the whole hog and try to provide hooks to the 16x5x code.
Is this likely to turn into a time consuming operation do you think? One
thing I'm concerned about is that IDTs are a bit of at unknown at the
moment to me. I kind of assumed eCos got these set up correctly
so that I wouldn't have to ?
Regards,
