Yes, and that bit I copied from the first series a year ago. I don't
remember why, but IIRC that was necessary to let the SDP stuff work at
all. Maybe the reset function was called under different circumstances
back then. I'll take another look.

I find it a bit weird that the auxiliary functions don't work when the
interface or the link is down.

Thanks,
Richard
