PySerial & RXTX query

I have had no success with opening a serial port (device is a Prolific USB
to serial comm port [COM9]) from Jython (2.7) using PySerial (tried both 2.7
and 3.1.1) and the RXTX replacement for javax.comm on windows 64 bit.  I
have tried the usual googling for examples but found no really helpful
jython specific ones.  If anyone has an example program that works, I should
be really grateful to see it!

It all works fine in Python 2.7 !

Thanks in advance,

Graham
