func main() {
	fmt.Println("Launching server...")

	ln, _ := net.Listen("tcp", ":8081")
	conn, _ := ln.Accept()

	for {
		message, _ := bufio.NewReader(conn).ReadString('\n')
		fmt.Print("Message Received:", string(message))

		newmessage := strings.ToUpper(message)
		conn.Write([]byte(newmessage + "\n"))
	}
}

	for {
		reader := bufio.NewReader(os.Stdin)
		fmt.Print("Text to send:")
		text, _ := reader.ReadString('\n')

		fmt.Fprintf(conn, text+"\n")
