Unless you care about POSIX compliance. IIRC baud_base and whatever's the
option to specify divisor allow you to use any clock frequency on your
serial port -- as long as hardware supports it. Very neat, but non-POSIX.
Which means if software relies on it, it's not POSIX compliant. Conversely,
software that asks for 38400 is POSIX compliant and (hopefully) portable.
So, you're suggesting that POSIX compliance is a bug, and so is
portability :-) -- well, not exactly: that absence of non-standard and
non-portable features is a bug.
Just kidding
