I don't want to dismiss the article entirely, but most embedded systems do not use a real-time clock (RTC). Most applications for these type of "islands of automation" provide simple sequential control that do not require the accurate date and time stamping that could be a problem for Y2K. The higher end embedded system that has an RTC may have a problem but only if it uses the year function or sends the time stamped year data to another system that relies on that data to initiate an operating function. That someone would use 00 or 99 as EOF characters is immaterial. Those characters will appear throughout any data transmission as real values, instructions or other data in any event. While this could well be a serious problem for some companies, a lot of hype and misinformation is being passed. I recall seeing a news article that said "pace makers" may cease to operate! Makes good fodder for the less scrupulous seller of Y2K solution services. Regards, John
