(213) 453-8649 Don't do this! Your keyboard and or computer can be damaged by unplugging and re-plugging with the power on. They were not designed to allow this. I am surprised that anyone would recommend as crude a solution to any problem as this. I don't know how VP/ix treates the keyboard hardware, but I have written a correct interrupt handler for the keyboard hardware under DOS and it is not easy to get everything right. I doubt that many handlers for the keyboard make use of the error detection/correction sequences mostly because it is poorly documented and it seldom would make a difference. The keyboard software could be robust. I am guessing that contacting the correct people at SunRiver and Interactive would get this cleared up quickly. If others have this kind of problem, then its software. If you are alone, I would bet its hardware. -- Doug Ingraham (SysAdmin) Lofty Pursuits (Public Access for Rapid City SD USA) uunet!loft386!dpi
