individual device timeouts

[artmeln]

It would be useful for every device to have its own timeout that can be set in the adapter depending on the method called.
For example, I'd like to be able to set the XYstage timeout to 1 sec while setting motion parameters, then to 'enough time to move' sec for SetPosition commands. At the same time, the timeout for a different device, say a shutter, would remain unaffected.
