Title:
  stty -F /dev/ttyUSB1 9600 sets speed as 300 not 9600

Status in coreutils-from package in Ubuntu:
  Won't Fix
Status in rust-coreutils package in Ubuntu:
  New

Bug description:
  Terminal input/output:

  $ stty --version
  stty (uutils coreutils) 0.2.2
  $ stty -F /dev/ttyUSB1 9600
  $ stty -F /dev/ttyUSB1
  speed 300 baud; line = 0;
  hupcl clocal 
  -brkint ixon -imaxbel 

  Speculation about cause:

  Values in glibc/glibc/sysdeps/unix/sysv/linux/bits/termios.h have
  changed between the version of glibc used in 24.03.3 and 24.10. Is it
  possible the nix::sys::termios crate used by
  uutils/coreutils/blob/0.2.2/src/uu/stty/src/stty.rs still has the old
  values?
