We at A T Engineering have been using the Intelliport-6 smart serial board with SCO Xenix/386 and Everex Step 386/20 motherboards. Our in-house use of these boards has been relatively trouble-free. Our customers, on the other hand, have had big problems, and we're mystified as to the cause. The primary symptom of trouble is that the board will stop working after hours or days of continous operation. The flashing LED's on the board freeze. A puzzling item: if the system is rebooted, the driver CAN'T FIND THE BOARD. At first, we thought it was a bad board or three. But now that it's happened at at least six different sites, and at some problem sites three times in a row with three different boards, we are beginning to suspect that there is some problem intrinsic in the system configuration. But here's the best part: When we swap new boards for the ones that stopped working, and try them in-house, many of them work without problems. This odd behavior has made the search for the problem's cause rather difficult. There are only two differences between the customers' machines and ours: 1. Some of our customers have Rev E motherboards instead of Rev G. 2. We usually run our main Everex with the cover off. So, what's the verdict? Have YOU had similar problems? Have you used Intelliport-6 board without problems? In either case, please E-Mail your comments; I will summarize to the net. -- Chip Salzenberg or A T Engineering Me? Speak for my company?
