title: Redirect telnet 23 to COM Port via WIFI
body: <p>I bought an Bluetooth  ELM327 to read codes out of my cars diagnostic ports</p>
  
  <p>I connect to it via Bluetooth in windows and it makes a serial-over-bluetooth com port 4 
  which any application running on my windows will connect quite happily.</p>
  
  <p>I then found a few apps for the iphone and android etc that connect to these ELM gadgets via WIFI and not Bluetooth (because for some reason you cannot pair to these devices of iphone)</p>
  
  <p>Now obviously I can buy a WIFI enabled ELM327 - but it costs £130 and my Bluetooth one cost £15</p>
  
  <p>So after reading about this a bit I found out that the WIFI enabled ones you connect up as ad-hoc network and the smartphone(iphone) app tenets in port 23 that relays normal serial commands.</p>
  
  <p>So obviously in the WIFI enabled one there must be some processor that runs an nano-os with telnet and some rs-323 translators and not sure what else.</p>
  
  <p>How, using Windows 7 will i be able to relay any incoming WIFI requests for Telnet port 23 to my COM 4 that is connected to my Bluetooth ELM327 .. </p>
  
  <p>As this is surely all that is needed by the Smartphone app.</p>
