This is broken. BOTHER can be set with a perfectly valid baud rate that could equally be represented by B9600 say.
If you are stuck with limited ranges then
switch(baud) { case 9600: case 4800:
etc
and don't worry about BOTHER, it's entirely transparent to you. The core kernel code will provide you with a baud rate number, the re-encoder will always do the right thing.
A driver should never care about BOTHER or any of the baud bits in the termios structure directly.
