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?
