Matt, I agree with your proposed dos packets, but I would also like 
to see a simple way to implement the one that checks for characters
to be read (See if any are available) on the serial port. 
    I would like to be able to access the serial port like this:

fp=fopen("ser:","r");
   (error check here)

while( (status=any_chars_to_read(fp)) != 0)
     {
      c = getc(fp);
      do_stuff();
     }

do_other_stuff();

---------------------


Maybe there is a simple way to do this now, but I sure haven't found it
yet. I need to do this to be able to write a Eprom programmer driver,
( I use a B&C microsystems 1409C ).  I think I could implement the 
above using the serial device, but I really haven't gotten into the
devices and exec deeply enough to understand how to do it yet. Any
body out there have any good ideas? Thanks for any help!
