L4/Linux communication with another L4 Thread

[GLeibrock]

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
