Ok, i see. But still:How can i get then information if the motors are running at the moment, or not. Without doing periodic scans on the PACT fields ??

But i thought it is "bad style" to do this synchronous with such large delays ? ( I had to define huge timeouts in the protocol to get it work...)This rule of not doing synchronous device support for devices with long delays applies to writing device support. If you are using StreamDevice (which I assume), your device support is not synchronous - StreamDevice and ASYN support below are working asynchronously and take care of the gory details for you. The port that you are communicating with will be locked while a protocol (like your move command) is running. But that is fine if the device can only use one motor at a time. Cheers, ~Ralph
