Would anyone like to share their experience with or opinion of QNX? We are considering going to it for our PC-based control systems. Specifically, is the message-based architecture as good as claimed? Is the interrupt response time as good as claimed? What about support and third party products? I know that a new POSIX-compliant version of QNX is about to be released; any opinions on that? -- Charlie Kester | cgk@chinet.chi.il.us | "Wretches, utter wretches! 1503 Larson Street | | keep your hands from beans!"

We have it embedded in one of our products, and we are also using it in several other process and machine control applications. In addition, the development environment gives us a lot of flexibility. It is common for us to include a modem in every new application, and we use it for remote debugging, instant training, etc. In case a problem develops on a remote installation, we can call in on a modem, and connect up with any node on the network, using its screen and keyboard functions to locate and correct problems. This is not a unique situation -- I can give you lots of examples of large, well-known (Fortune 500) companies that are using QNX in very demanding applications with great success. I have some other information (14-16 pages) that I can FAX to you, if you are interested. It is a technical overview of the OS, plus a couple of magazine articles. I'd be happy to discuss any of this in more detail over the phone, if you wish. Or, I have some information I've collected that I could E-mail to you, although it's a little dated. I saw the first of the ads for the POSIX-compliant version of QNX in Byte magazine yesterday. It's being advertised as a new real-time version of UNIX -- I never thought of it that way, but of course it's true. I don't think the new version is being introduced until the annual conference in Ottawa on June 17-20. I have attended this conference every year since '88. It is a first rate affair, with attendees from around the world. There will be a great opportunity to meet the developers, the users, and many third party vendors. The only problem is that the attendance is being limited to 550 people, and it's filling up fast. Also, this is prime tourist time in Ottawa, so hotels are really busy. If there is any chance you will try to go to the conference you should make arrangements quickly. Feel free to contact me at any time. =#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=# Dick Gardner -- Eastman Kodak Co.
