title: Reading data with TCP indy 9
body: <p>in my project I need to developp server receiving frames from GPRS/GPS Box and decode theses frames to extract relevant data as latitude , longitude and more</p>
  
  <p>the first part (TCP connection and receiving data) is done , the problem I had is with decode data, the firmware of GPRS box  send data not in string format but in hex format , so the methode I used (currentReaderBuffer) ouput the frame with string format , let me explain with real example : </p>
  
  <p>The data sent from GPRS BOX is :   0d 0a 1f 52
  data received using   currentReaderBuffer is : #$d#$a#1fR
  the problem is how can I know if the caracter #$d correspond to 0d or each of the caracters (#,$,d) correspond to each ascii code  </p>
