Error in creating TCP client in lua

I am trying to create TCP client in lua

local host, port = HOST, PORT
local socket = require("socket")
client = socket.tcp();
client:connect(host, port);
client:send("Hello User");

this works fine but when i add 

while true do
    local s, status, partial = client:receive()
    print(s or partial)
    if status == "closed" then break end
end

to read data from socket it block total execution of code.

By default, all luasocket I/O operations are blocking. You need to use socket.settimeout(0) (settimeout) to disable blocking. You can then check for "timeout" value returned as status and act accordingly.

Depending on how the data is being sent, this answer may be relevant as well.
