title: How to talk to MSP430F through DLT/645 protocol?
body: <p>I have the following datasheet that partially talks about the DLT/645 Communication Protocol which is a Chinese protocol for having Serial Communication.</p>

  <p>There is GUI for such device and can talk to it through a serial port and collect the required data. However, I would like to start from scratch and make my own version of GUI!</p>
  
  <p>I know that first I need to know the command to ask the meter to send its reading at phase 1.</p>
  
  <p>In this document on the page 22, it is said that from the GUI to the meter if I put 0x61 0x00 I will get the phase I reading!</p>
  
  <p>My question is how to use these HEX numbers to get phase 1's readings not on their own gui but on a terminal let's say Hyper terminal or so?</p>
  
  <p>What would you advise me to start this from?</p>
  
  <p>Thank you.</p>
