L4/Linux communciation with another L4 thread

@postmaster: Sorry for any inconvenience. had problems with my email application Hi, I am quite new to L4 and I did succeed in writing a server task for L4 and to call this with another L4 thread/program. (Did start them by modifying menu.lst). But I did not find out how I could communicate with an L4/Linux program and another L4 server. I want to send/receive data. Is there any code around that copes with this feature? Thanks, Gerhard
