title: How to make a port of some linux command for Android OS?
body: <p>I'm looking for a way to use CDMA modem in my Android device.
  Modem is recognized successfully, pppd is present however it lacks a 'chat' program.</p>
  
  <p>Could anybody explain what steps are involved to port some linux program to Android ?
  I want to know just basics, how to achieve this.
  I saw that people create custom linux dists for Android, so I suppose I need to look in that direction.</p>
  
  <p>Thanks a lot !</p>
