Does not support "non-standard" baud rates

[H. G. Parra]

Although not requested, some people use "non-standard" baud-rates depending on hardware and crystals.

Examples:

Support added for Windows in 1.0.4. Still need POSIX support? See #16

I'd like to see Linux support for custom baud rates (I need 250kbps fora commercial device). About to try a gist that I found which purports to do this.

PySerial can set up to 4Mbps in standard values in this way.
