Java SE (Java Platform, Standard Edition)

Hi

I am trying to use the ircomm2K driver ( which turns an IrDA port into a 'regular' serial port ) under windows 2k Pro and XP home, with Java 1.4.2 (and the latest javax.comm).
the SerialDemo sample from Sun is not working ( eg no char appears on the receiving end ).
In fact not a single java programm I tried worked.

Any clue anyone ?

a few details :
Of course, the systray icon shows me the PC are in range.
the PortMon utility from sysinternals.com shows the char are sent to the serial port.
the COM port are 6 on one end and 7 on the other.

Thanks in advance,

--Philippe
