Hi Niklaus,

Excellent.

Right - if you only reimplement the methods that we use locally then you
should not need to touch anything basically.  This boils down to
providing a "remote_power" and "connect" utility.

It seems like this is a good opportunity to work on this end of duts.
Looking at the code it was pretty clear that it could not work as
expected, so I started somewhat cleaning up around here and freshened my
memory on how this is supposed to work at all.  So do a "git remote
update" on your git tree and pull in the latest changes...

In spite of what I wrote earlier - the whole 'configuration' stuff
pivots on config/configs.tcl.  In here we have configuration
descriptions.  The _default must be first and initializes all "slots"
which can be overriden in subsequent duts_configs.

So If you want to only swap in your operatios, do something in there
like: 

duts_config {
            cfg_device_ops "config/my_ops.tcl"
}

and provide the config/my_ops.tcl.

Sorry my previous answer were based on incorrect memories.

Cheers
  Detlev
