[LUA][GPS] Command for gps host?

Hello there,

I'm running a private hamachi server for my friends and myself. I run it off my laptop, which means, the server can't be 24/7. I want to set up a startup floppy disk, that will cause the computer to startup, activate the rednet (rednet.open("left") in my case), and then use the command gps host x y z, depending on which computer is where, that way, each time I start up the server, the computers automatically create a gps network, for my turtles. However, I can't figure out how to make the lua code for gps host. Can someone help me out?

create the file startup with this content

rednet.open("left")
shell.run("gps","host",x,y,z)

you don't actually have to open a modem, the gps command detects them and opens them automatically

true that i wasnt realy thinking abou that when i was posting this because he said he wanted to open a modem i thought u had to :)/>/>
