I also suspect that the sync ports are designed for continuous use and
cannot be setup for on-demand use.
I am starting to realize that this may have been a major oversight in
buying an OR-LS to use with an external ISDN TA (for on-demand use).
Wanted to use Livingston but OR-U does not have a POTS port!
