OTWINCFG exits before I get a chance to enter the filename so I guess it doesn't make any difference what my intention was, but mostly I wanted to save the new parameters back over the old file name. The abrupt, premature, exit occurs most often on the Dell laptop when a usb/db9 serial adapter is plugged in, but not being used. I think it also occurs when the adapter is not plugged in-- I will recheck this further. I haven't observed this on my desk top with a real serial port (DB9) on it in the last day or two. Elmer
