Can an implanted comlink be equipped with a sim module or do you need to get the implant version? Can an implanted comlink be equipped with a skinlink to interface with other skinlink equipment?
Dose Direct Neural Interfacing control of a comlink allow you to silently make and receive calls? Can you see images and hear sounds without audio or visual devices if you have a DNI able to feed information directly into your brain ala simsense?
What exactly dose DNI do? The information on know-softs says that a sim module and a datajack are considered a DNI and the information on cybernetics says that implants are controlled that way.
I would actually not require either a) skinlink or b) direct neural interfacing for an implanted comlink. Skinlink runs the signals through your bioelectric field, right? If it's implanted and taking up essence, the commlink is already connected to your bioelectric field. Skinlink, in short, is for those gizmos that you do
not have implanted, but that you don't want make susceptible to hacking.
As for DNI -- if you have a datajack, well, there you are; if you have an implanted commlink, you probably have a datajack. I would
presume that the datajack was automatically connected to the implanted commlink. If not, then what are you doing?
I would, however, require each 'link necessary for the person to perceive in that sense 'spectrum' while in AR. They can, of course, drop immediately into VR if they have the sim module up and running, and get the feed that way -- but I wouldn't allow an AR feed to be dumped directly into the brain without serious penalties. The various sense links are there so that the character's sensorium doesn't get overloaded.
