This question is not strictly speaking connected with this thread but please bear with me. The last comment I read was about a a1000 owner whose RS-232 port was "already overloaded with a printer, plotter, and modem". My question is: Since most RS-232 peripherals run at 9600 baud or less (printers, plotters and modems<mostly>), would it be a neat hardwaresoftware hack to allow multiple 'channels' to use the 1 megabit bandwidth of the Amy RS-232 port? I'm VERY hazy about the details but I have this glimpse of the Amy hardware running flatout with a multi- plexer of some sort running off it splitting up the bit stream say eight ways to eight UARTs(?). Maybe Ser: would have a problem with it. But couldn't a custom device driver handle it? OK, OK. Go ahead and let me have it. *WHY* won't it work? Dana
