I'm not a win32 guy but from my observations ('forced' for $) the w32 
kernel handles this.  Win32 is not a problem.

Actually while looking at w32 I saw it does some neat things.  They had a 
really great guy doing serial programming.  I had to look at w95, 98, nt, 
xp, .. it was sad watching it slowly degrade.  It is still decent though.

It is very different from POSIX termios but early on it was _very_ 
respectable at the rs232 layer.
