I've been reading the wiki for about few hours now and i stumbled across this:
http://wikiti.brandonw.net/index.php?title=83Plus:OS:Remote_Program_Execution
and i have a few questions. So basically what i can do is silent link to another calculator to upload a BASIC program to it and then tell it with some proper ASM magic to execute it? If so i must try it out. I have tried to find some more info on silent linking but without any effects.

Transferring files by silent linking is pretty easy to do via ASM, and interestingly enough, simulating silent linking is how jsTIfied and many other emulators transfer files onto emulated calculators. Getting the remote calculator to execute that program is harder, and has been the subject of occasional idle debate around the community, as it could obviously (if you're unethical) be used to create a self-propagating "virus" program. One thing you can do is use the silent linking system to send keypresses, so you can send the sequence of characters for "Asm(prgmYOURPROG" to execute it after silent-linking it across.
There are actually numerous ways to do this, see
http://brandonw.net/calcstuff/keyscnlnk.txt .
There's a command for remotely executing a program or Flash application, and even one for transferring a program which it only stores temporarily (as TempProgObj) and executes it.
That way you don't need to deal with sending keypresses, or clearing the homescreen's history of you executing it, etc.

Thank you, this helps a lot!

Really? A virus for a calc? There isn't even a point of doing that, the only thing one could do is to keylog or crash the calc.
So i guess a cool thing to use this in would be some kind of communication system between calculators.
One could send 23h, 6Eh To get the calculator ID, then check if you allready know this person.Then 23h, 06h to send a string variable containing the message.
Just a few follow-ups.
You send these bytes by calling keyscnlnk, but where are they supposed to be?
Where do you get the data? (For example after requesting the calculator ID)
