Habe eben das hier in den Lynx FAQ´s gefunden:
Q. I hear there was a ComLynx port on the Atari Jaguar.  How did that work?
   Could I connect my Lynx to it?  Was there a Lynx adaptor for the Jaguar?
A. The Jaguar does not have a ComLynx port per se, but has a ComLynx signal
   on the system bus.  An expansion port add-on would have made the port
   available, and developers had announced plans for such accessories.  It is
   possible to daisy-chain multiple Jaguars for multiplayer games into a
   "Jaguar network".  In theory, it would have also been possible to connect
   Jaguars and Lynxes, though no plans for cross-system software were ever
   finalized.
   There was also talk that the Jaguar's ComLynx signal could allow Lynxes to
   be used as peripherals: software could have been developed to allow Lynxes
   to be part of a Jaguar game as "smart" controllers.  Again, no actual
   plans were ever announced.
   An adaptor to allow the Jaguar to play Lynx games was never planned.
