Receive UDP string

[Diggerz]

Hi I'm after a similar function but require a TCP connection to ensure retransmission of any lost packets. Is there an example of a TCP server?

is there anything wrong with this from the lua socket example? can it be improved for the lm?

Code:

if not server then
-- load namespace
socket = require("socket")
-- create a TCP socket and bind it to the local host, at any port
server = assert(socket.bind("*", 7777))
-- find out which port the OS chose for us
ip, port = server:getsockname()

-- print a message informing what's up
log("Please telnet to localhost on port "..port)
log("After connecting, you have 10s to enter a line to be echoed")
-- loop forever waiting for clients
while 1 do
  -- wait for a connection from any client
  local client = server:accept()
  -- make sure we don't block waiting for this client's line
  client:settimeout(10)
  -- receive the line
data, err = client:receive()
    log(data)
  -- done with client, close the object
  client:close()
end
end
