Yes, it works at 115200. I have done it and other have as well.
The ARM AEB board (the $150 board they used to sell) has a bug in it and it would not follow the protocol so switching to a higher speed fails (thus it only works at 9600).
We tried to ask ARM about this and the answer was that we should buy the new $250 development board.

With the current versions of Cygwin it should work fine.
But if you are using a b.20 or some other old version of Cygwin you may encounter problems with serial lines. It gets worse the higher the speed you use.
In this case, just grab the latest Cygwin and everything will be fine.
