At least that what it >does for me... Yes, but not all terminals provide the ability to copy one screen to another, thus making the screen switching solution terminal-dependant (and therefore unusable by the general public). One solution would be for the kernel to map all characters written to tty's, but this would involve linking terminal capability into the kernel which would mean re-linking every time a terminal was changed around (yuck!). ----------------------------------------------------------------------------- Michael Stefanik, Systems Engineer (JOAT), Briareus Corporation UUCP: ...!uunet!bria!mike "If it was hard to code, it should be harder to use!"
