Hardware...

A friend of mine has a problem with the 8250 com chips. It appears that
the chip will reset sometimes when the machine is running for no apparent
reason. He wrote a small prog that verfies this, monitoring the chip. He
is certain the reset input to the 8250 is not being changed. He called
a manufacturer whose rep said there are various versions of the 8250 with
various bugs, one of them being that, with a certain combination of chip
select and address line inputs to the 8250 will cause it to reset. 

Anyone have any experience with this?

Thanks! ...Gord (gord@geac)
