The is rt_loopback, but TDMA is not working over this device (in case you want to test the WAIT_ON_SYNC, replace it with some periodic delay). Unfortunately, it's not possible with the current rtnet script to start only the loopback device (it's always started together with a normal network). Fortunately, it's easy to do this manually: just load the core modules rtnet, rtipv4, [rtpacket,] and run a "rtifconfig rtlo up 127.0.0.1". If you need the system timer being started (that's likely when you want time-triggered interaction), also load rtcfg. Jan
