The only solution which I have found that gives satisfactory results is the Nudata(TM) Non Aborting Serial Port Adaptor. This is a little black box that cost about $90. It has smarts onboard and allows the BREAKs to be sent from a terminal or terminal server port. But it monitors the DTR line, if it drops then the box blocks all input, thus if a terminal server sends breaks at power down they are blocked when DTR drops first. There is a timing issue here but it seems to work, I suspect they have a transmission delay built in to catch the fault before the BREAK is sent but I don't know this for sure. The beauty of it is that we can still use BREAK to halt the system if we want. If the terminal server looses power all our Sun's DON'T halt. It would also cover off any problems of the line being cut and looking like a break as long as DTR is cut at the same time. The only down side is the price tag. "John R.
