*** Interrupt Driven I/O ***

*** How I Tried to Chomp 960 Times a Second and Lost***
Can anyone in "note-land" offer any words of wisdom/advice on the
problem of writing interrupt-driven I/O between an IBM-PC and an RS232
communications port? The thing I am attempting is to write an intrrpt
vector that is serviced anytime a byte arrives over the RS232 line.
In general I am trying to write a 9600 baud RS232 interface, which
"appears" to be impossible without going to an interrupt-driven
scheme. I've tried working thru the constructs provided in CI-C86
("C"), to no avail at 9600.
