On Linux, man termios gives lots of API details.

On NetBSD and FreeBSD, that gets an overview.  man tcsetattr gets the API 
details.

If you use stty to change things, the new info is sticky.  So if you have a 
program that is all set to go except that the baud rates aren't right and 
that program doesn't smash the baud rates, you can set them with stty and 
your program should work.  I haven't tried it with split baud rates, but the 
normal (non-split) case works.

If your gizmo uses simple ASCII, you can test things with cat /dev/wherever
and things like this on another terminal
  echo "blah blah..." > /dev/wherever
