title: What serial file transfer protocol to use?
body: <p>I'm looking for some input on witch file transfer protocol to use over a serial line. I want to be able to transfer files of max 200 Mb size over a serial line (RS232) in both directions, but only one of the machines needs to be able to initiate the get/put (think master-slave).</p>
  
  <p>The protocol also needs to be:</p>
  
  <ul>
  <li>Easy/simple to implement since I would need to write both client and server myself (limited, embedded hardware)</li>
  <li>Fairly robust, fault checking/recovery etc</li>
  <li>At least somewhat standardized, in case I need to get a third party to implement it on some other hardware</li>
  </ul>
  
  <p>Kermit? TFTP? Simplest possible home brew? What do you think?</p>
