title: Netcat Android missing UDP support
body: <p>I would use Netcat with UDP protocoll on Android, but Busibox based nc not  supports UDP.</p>
  
  <p>~$ nc -u -w1 -p10000 192.168.178.31 10000
  nc: invalid option -- u
  BusyBox v1.23.2-Stericson (2015-04-10 10:51:32 CDT) multi-call binary.</p>
  
  <p>Usage: nc [-iN] [-wN] [-l] [-p PORT] [-f FILE|IPADDR PORT] [-e PROG]</p>
  
  <p>Open a pipe to IP:PORT or FILE</p>
  
  <pre><code>    -l      Listen mode, for inbound connects
              (use -ll with -e for persistent server)
      -p PORT Local port
      -w SEC  Connect timeout
      -i SEC  Delay interval for lines sent
      -f FILE Use file (ala /dev/ttyS0) instead of network
      -e PROG Run PROG after connect
  </code></pre>
  
  <p>I'm on Lollipop (Samsung Note3 N9005). 
  Maybe Busybox, netcat android is the reason. </p>
