forging raw bytes and sending them over UDP

Hello,
I need to forge UDP datagram with specific 8 bytes length data payload.

I have to control a showcontrol proDAP (interface to control a big DMX network) by sending those bytes to trigger sequence etc.

Using wireshark to verify that, I figured out I cannot do that with udpsend.

So I discovered aka and http://cycling74.com/forums/topic.php?id=30765
But using windows on all my installations, I can't use aka (or I didn't figure out how to use it)

Any ideas? trick ? tips?

I developed some mxj objects to send and receive raw UDP bytes for Art-Net DMX control. Have a look at the source, it should be pretty easy to modify for your purposes.

using sadam.udpSender, it works very well
I verified it on wireshark

thanks a lot for the 2 java.
I'll check them too !
If I think about using them, I'll ask you before!

thanks a lot !
