It was designed to be uni-directional back in the XT days, but is now used bi-directional, most notably for the UPDATE LEDS command, which is why you're experiencing this at VT switches. ``Bus arbitration'' is poorly maintained for the keyboard bus (it's a simple ``first comes -- first gets'' kind, with no good means to recover from an access clash). Btw., the latest version of SCO got consistently stuck when i ran it on an HP Vectra (a supported platform!), and hit ``Caps lock''. :-] -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
