Java + multiport serial card

[RFZC]

Hi
We have a small visual basic application to collect data from controlers.
PC has Windows XP Professional and has a multiport RS232 card.
We have to replace the old application and we will develop the new one using Java.
We understand that Java does not use Win32 Serial API.
Has one of you any experience with Java and multiport RS232 card?
We have reviewed data sheets of some multiport cards and we have not found reference to JAVA, they only mention C, C++, VB, or .NET

You will probably have to write it in C and use a Java/C interface to talk to it.

Thanks for your answer
When you say "will probably have write it in C", means that it is not possible to do it with Java?

What about 'Java Communication API' ?

Here is a link to it :

I have reviewed that Web page and I found that implementations of the API are currently available for Solaris SPARC, Solaris x86, and Linux x86.
Actually I know that Java manage the serial port with its own API. But, does the Java communications API will recognise a multiport serial card?
I need to import multiport serial card, so it is no easy to prove and give back it if result will be unsuccessful.
I have to use Java, for standard reason. Only if I show evidence that its unreliable to choose Java for this project we could move to VB.

If you want to use it on Windows there is another library RxTx (

that could be used alone or with JavaComm.
