calling a program on a peripheral

hi,
I tried searching for the answer, and didn't find it, how do you call a program on a peripheral?

For example, say I want to have a master turtle walk on top of a set of slave turtles and run a program on all slave turtles.

I want to do the equivalent of typing out these two commands:
"rom/programs/read-image/bmt 00"
"rom/programs/read-image/bmt 01"

local numTurtles = 2
for turtleNumber=1,numTurtles do
local montageNumber = string.format("%02d", turtleNumber-1)
turtle.forward();
peripheral.call("bottom", "turnOn")
peripheral.call("bottom", "os.run", "rom/programs/read-image/bmt", montageNumber)
end

You can't. Try using rednet to send them the commands.

The only way I know of is to have your master turtle drop a disk drive next to a slave turtle, insert a disk, rename the program you want to use to startup, then boot the slave turtle.

It's not pretty, but if i recall correctly it does work.

So, how do I make all the slave turtles listen to rednet? call turnOn and run a custom startup program?

yea, thats how i did it
