Hi Norbert,

yes it works, use the RXTX library (rxtx.org). You can use either the  
expensive Keyspan USB->Serial adapters with their driver or  
inexpensive ones based on the PL2303 chip (e.g. from Digitus). For  
the latter, there is a driver from Prolific (prolific.com.tw) and an  
opensource version
   http://sourceforge.net/projects/osx-pl2303/

In my experience the PL2303-based devices often don't transmit the  
first byte sent after closing and opening the serial line, you should  
send a dummy byte first.

For code development and more information concerning use of RXTX, you  
can also have a look at eslide/ijStage
