KPeriph socket example

local p = peripheral.wrap("side")
local handle p.socket_create("host", port)
p.socket_setAutoFlush(handle, true) -- saves you calling socket_flush(handle) after using socket_write()
p.socket_write(handle, "SomeLine\n")
local e, side, handle2, line = os.pullEvent()
if e == "socket_connectionClosed" and handle == handle2 then
    print("Connection closed")
    return
elseif e == "socket_line" and handle == handle2 then
    print("Line received: "..line)
end
p.socket_close(handle)
