I'm writing a Terminal Glasses(OpenPeripheralAddons) script, to convey time, power status and other information to my HUD.
I have a advanced computer with the Terminal Glasses Bridge and a wireless modem attached, and another computer next to my Power Storage. I want to send the data via rednet, but I can't wait and listen via os.pullEvent or rednet.receive. I already tried the parallel API, but it seems like the second function never runs, even when I yield.
To sum it up, I need to receive rednet messages in the background somehow, or stack them(stop the event's removal) and check each cycle.
Any help is appreciated.
