[comp.unix.xenix] Multi-channel serial cards for ATs

philip@axis.fr (Philip Peake) (10/26/87)

I am looking for some information on multi-channel serial cards
(intelligent, DMA) for IBM PC/ATs running UNIX.

We are thinking about investing in several hundred of these cards
per year, so we would be interested in any comments on the following
points:

	1)	Availability, remember that we are probably
		interested in buying at least 100 at a time.

	2)	Price (are quantity discounts available etc).

	3)	Drivers available - we need: SCO XENIX, Microport unix,
		and Microsoft XENIX.

	4)	Performance - this is what basically rules out
		'dumb' cards - the interrupt overhead is too high.

	5)	Experience with the cards. Have you ever used one ?
		Is it as good as the manufacturer claims, does it
		work reliably etc ?

So, if you can give me ANY information on this topic I would be
pleased to hear from you - by email or whatever else, preferably
not to the net; I don't suppose most people want to read the answers
to my questions.

If anyone is interested in the results I get (if any), please ley me
know, and I will keep you informed. If more than about a dozen people
are interested then I will post a resume to the net.
