PQ>    That's a cop out! I can get those libraries, but I wanted to do it
I'd hardly call it a cop out.
Your original post was just asking about doing serial I/O.  That
generally implies drivers that would work on all/most uarts, with and
without the FIFOs enabled, detecting and working around bugs in some
versions of the UARTs, and so on.
And since there are such a wide variety of controllers and situations
that you would have to deal with, it becomes a lot of work in writing
it, debugging it, and maintaining it.  That's why it's better to let
others do it.  They've already had to go through all that.
Your message didn't say it would for a very specific use with a single
controller.
PQ>    I assume all I need to know is which address's to IN & OUT to
PQ>and what is at those addresses. then I have to right all the serial
PQ>access etc.. I'll need to link the serial ports to the DSP chip and
Well... There are a few more things.  Like dealing with the FIFOs,
making sure your uart even has a FIFO, setting up for the serial I/O
interrupts, etc.
