Problems with javax.comm in a usb multiport

Hello,

I'm using the javax.comm library to communicate from the serial port. The program works fine connecting the serial port to the machine I want to connect.

But if I connect the machine to the serial port in a multiport usb the program hangs in the close port statement, and I don't know how to solve this problem. It is like the library couldn't do the close statement, or couldn't finished. (I have verified putting in my program System.out.println statements before and after the close port statement).

What can I do?

Thanks,

David.
