[rtl] Would RTLinux work for this application?

[Donald Gaffney <gaffney@salus.med.uvm.edu>]

Hello,

I just discovered RTLinux yesterday, so please pardon my newbie-ness.

I have the following feedback problem:

	- Collect 4 analog signals
	- Run some PID calculations
	- Dump 64 bits (digital) to an external control system

This needs to occur at least every 100 microseconds (10 kHz).

I have hardware that can do this (National Instruments PCI MIO E
series and PCI DIO 96 cards in a Dell Pentium Pro 200 MHz system which
can take another processor), but it simply won't work under Windows
NT with NI-DAQ drivers. NT is _not_ suitable for real time work, I've
learned this the hard way.

Now I need to re-tool and try to get this system to work. I can probably
use DOS, I'm also looking at other hardware solutions and other RT
solutions for NT.

I've read through a lot of material since I found the NT problem. I've
found that most systems, including RTLinux based systems, operate in
the ms or 10s of ms time domain. Would MP RTLinux work for this 100
microsecond project?

Hoping Linux can dig me out of another hole,
