This raises a question I've been wondering about for some time. While
the kernel and the serial driver API support arbitrary baud rates,
termios doesn't AFAICT.
How does one use the standard POSIX serial port API to obtain an
abritrary baud rate?
The only way I can find to get arbitrary baud rates from a user
perspective is to use the ASYNC_SPD_xxxx mechanism.
