/***************************************************************************/
/* macOS termios.h unfortunately just provides constants for baudrates
* up to 230k, so we add the missing constants here. Regardless, that
* most of the high baudrates needs special handling (implementation in
* tcsetattr_custom()), we want to provide the values here to have them
* available for term_baud_up()/down().
*
* FreeBSD 11.0 termios.h has 460k and 921k but misses e.g. 500k and >=1M.
* OpenBSD 6.2 termios.h is missing all >230k (like macOS).
* NetBSD 7.1.1 do same as FreeBSD 11.0.
* DragonFly 5.0.2 looks same as OpenBSD 6.2.
