And that's very uncommon. Of course, there isn't much I can do about it, since you didn't tell me what you're running. I'd suggest you take a look at http://www.lemis.com/questions.html. But I'd guess it's a relatively slow machine (386?) with a 16450 UART. Look for a board with 16550 UARTS; they're not expensive, and they should solve the problem. I've been monitoring a 368DX/33 which functions as an Internet gateway, and it had a lot of these overruns until it changed to 16550s. Since then there have been none. Greg
