I am at this moment using a Leading Edge model D with a direct serial line running at 9600 baud, with a Sytek box at the other end and I don't have any trouble when the switch on the back is set at 4.77 MHz. If your screen scrolls too slowly, try running something like FansiConsole to speed it up (I do). -- ------------------------------------------------------------------------------- Iskandar Taib | The only thing worse than Peach ala Internet: NTAIB@AQUA.UCS.INDIANA.EDU | Frog is Frog ala Peach Bitnet: NTAIB@IUBACS ! -------------------------------------------------------------------------------
