I'm stupid, it's pyserial
(a bit confusing, as the package name is serial)

Using SVN HEAD, Cygiwn 1.5, Python 2.5.2:
The backward compatibility with Python < 2.6 as implemented in serialutil.py does not work
The code line 10 ("bytes") expects an AttributeError exception, while the Python VM raises a NameError.
A quick fix seems to be:
except (AttributeError, NameError):

Ok, great, it works with [242], up to 3Mbps on my machine - thanks a lot.
I've added the following piece of code to enable or not the Darwin hack, depending on the actual pyserial version number. Please, let me know if there is a better way:
{{{
serialclass = serial.Serial

Sorry, I meant:
I've set up a clean Python installation (2.6.2), to be sure that no
previously *installed* modules get in the way.
I may have *forgot* something obvious, but I see no improvement:

Mac OS X TERMIOS API only supports baudrates up to 230400 bps.
Higher baudrates are not supported, and any attempt to use them ends up with an exception.
On Tiger (10.4.x) and above, it is nevertheless possible to use higher baudrates, using an IOKit-specific ioctl call.
I have not written a patch yet, but here is a code sample I use to circumvent the current pyserial limitation on Mac...

It seems the issue actually depends on the USB-RS232 bridge; on the USB key I just bought it's deadly slow; on the key I bought a year ago, it works as expected.
Maybe the PL2303 chip inside the USB key is different (H, HX, X, ...) ? Let me know if there is a way to report the chip version
BTW I just froze one of my two Core 2 (MacMini): after a small RS232 communication, the communicate...

Really a small cosmetic, trivial change; anyway:
The installer shows the following instruction sequence to uninstall the driver:
-open a terminal
-type: kextunload /System/Library/Extensions/osx-pl2303.kext/
-The command prompt ask for you administrator password
-type: sudo rm -r /System/Library/Extensions/osx-pl2303.kext/
