I am writing a program that reads input from the serial port, and have been
having problems implementing flow control.  I'd like to read the serial
port on the interrupts, but don't know how this is done on the Mac.  So,
that's my question.

How does one write interrupt driven code for the Mac? (serial port code in
particular)  If this isn't possible, I'd like any suggestions you might
have.  I had planned on using a ring buffer to read and write at the same
time, but this just isn't efficient if you can't read the serial port on
the interrupts.  Thanks for your help.
