There are two PL2303 drivers for OSX.  There are some fairly old 
official drivers.  The .hqx makes me think this is that driver.

http://osx-pl2303.sourceforge.net/

In my experience these drivers are much better.  I'm not certain, but I 
think one of the differences is something to do with sending break 
signals.

I will point out that the PL2303 doesn't do breaks entirely correctly 
(something about voltages I think), but breaks that work on many devices 
is better than nothing.
