Need support for additional non-standard serial baud rates

[shaydr]

I have a serial device capable of supporting 921.6Kbps however the current implementation of win32_serial_driver.rb checks for the requested baud_rate to be in the Win32::BAUD_RATES array and then raises an exception if not found.

The DCB structure supports arbitrary baud rates. I have tested a modification to the Win32::BAUD_RATES array where the addition of 921.6Kbps works with a target device.

Suggestions for Resolution

• Add Api to add additional supported rates programmically from target interface definition
• Ignore the check
• Add the missing non-standard rates [230400, 460800, 500000, 576000, 921600, 1000000, 1152000, 1500000, 2000000, 3000000, 3500000, 4000000].

I think adding additional rates is the best option, additional rates not expected to be added anytime soon.

_NOTE:_ the posix_serial_driver uses termios and it looks like 921600 is defined on modern linux distros and in the ruby-termios package

Dan - Are you planning on implementing this or should I?
