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
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.
