rednet help

Hi

I'm trying to create chat program with a client and a server.

I need help figuring out how to check for incoming messages and be able to write a message at the same time.
When I do rednet.receive() it wont let me write something that I could send to the server.

Here is the code:
Client

rednet.open("right")
rednet.receive()
read()

function send(msg)
rednet.broadcast(msg)
end

function read()
while true do
message = io.read()
send(message)
end
end

Server

rednet.open("right")
print("Server online")
rednet.broadcast("Connect to server with ID #2")
rednet.receive()
read()

function send(msg)
rednet.broadcast(msg)
end

function read()
while true do
message = io.read()
send(message)
end
end

You could handle the "rednet_message", "key" and "char" events to get the input and the messages. It would require you to handle the input yourself (you can't use read()). An alternative would be using the parallel api to run both functions at the same time, but it might make a mess in the screen if you don't move the cursor for each function to different places.
