   But 230400 and 460800 bps was already possible before that patch!
   It's only the POSIX speedsetting braindamage that disallowed that.

   I am running one line at 7812 bps and one at 76800 bps using a 460800
   baud_base.  That cannot be done using POSIX tcsetospeed even with your
   patch.  You would have to add an infinite series of Bxxxx entries to the
   silly table.

   The TIOCSSERIAL ioctl does it without pain, so I just use that.  Hopefully
   the POSIX folks wake up sometime and add a speed setting call that gets
   an integer argument that directly specifies the bitrate.

Yes, but it's much easier to get application programmers to support
230400 and 460800 if you provide a way to do it within the standard
POSIX framework.  I agree with you that the standard POSIX framework
is.... non-optimal.  However, backwards compatibility with old systems
was a extremely important for the POSIX folks, for better or for worse.

                                                - Ted

#define B38400 38400
#define B115200 115200

and so on. I don't think posix mandates that the numbers must be small
integers. And this way if the header files don't support B230400 you can
just use 230400 in your program.
