Hi.  I am currently trying to write a simple Turbo Pascal program on the
Rainbow that will act as a "smart" dumb paper terminal to be used as the
console on a bunch of MicroVaxen under Ultrix.  As the Rainbow is a MS-DOS
computer, I first turned to  the various MD-DOS books, articles, etc. to
learn about MS-DOS, interrupts, etc., but have found that the intended
audience there are IBM PC/clones.  I have not been able to find out any
hardware information on the Rainbow beyond the MS-DOS user's Guide, the
CPM one, and the Polycomm stuff, that comes with the Rainbow.  I need
to be able to read from the serial port as well as the keyboard at the
same time.  Various interupt schemes are possible, as well as polling, but
I lack the information to fully realize this using Turbo.  Please
send any suggestions etc. to me.  I am especially interested in a timer
interrupt or a way to easily poll the serial port without having to wait
for data.  Thanks.
