using wired modems and os.pullEvent()

how would I use an OS pull event and a wired modem attached to a peripheral? specifically how would I tell, using a chat box, get an input from user in chat and do something depending on what that is, I can do this by wrapping it directly to the computer, but I'm unsure of the process with wired modems. I guess basically I'm asking how to wrap a peripheral with wired modems.

while writing this I kind of answered my own question, just wrap it like a normal peripheral but instead of a side use the name foor example:

chatBox = peripheral.wrap("chat_0")

and you can use os pull events fine

So would this allow your computer to respond regardless of where you were on the map if you entered a !command ?
