I'm planning on using Java on the Linux side to access the FIFO's. The only way I can see doing it is to have some JNI glue to deal with the read() and write() calls since they involve pointers. Before I start I was wondering if there was a simpler way to do this, i.e. without resorting to JNI? Regards, Jim. --- [rtl] --- For more information on Real-Time Linux see: http://www.rtlinux.org/
