Openperipheral glasses commands HELP!

Hi Computercraft Forum,
I wanted to ask how the openperipheral glasses with the prefix $$ for a program.

How is it done?

please help me!!

when you say something in chat with $$ as a prefix while wearing the glasses, the computer linked to the glasses gets an event, one of the parameters of this event is the message that you typed into chat

How to find that event:

while true do
local event = os.pullEvent()
print(event)
end

Run this code on a machine with the bridge next to it, then type the $$ prefix while you're wearing the linked pair of glasses. This will tell you what event you need to look for (and possibly look up on google for an easier time)

Thanks
