This is exceedingly odd. As a power engineer in training I would say somebody did a really rotten job designing the power supply in one of your machines. Was there any other equipment on either of the machines's outlets? Poor power regulation aside, I don't see how a phase difference affected the serial port. I hope that in general at least this isn't a problem. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] . Trouble? e-mail to [EMAIL PROTECTED] .
