title: pc to pc communication using rs232 connected through optical link showing FRAMING ERROR
body: <p>I have set up a PC to PC optical communication link using RS232 Port.</p>
  
  <p>I have used 
  PC1 RS232 -> MAX232A -> Optical Tx/Rx Module -> MAX232A -> RS232 - PC2</p>
  
  <p>sending and receiving data using RealTerm software.</p>
  
  <p>but while sending data from PC1, some another data is received at PC2 stating Framing Error i.e. error in identifying start and stop bit.
  e.g - <br>
  Input | Output<br>
    1   |   g<br>
    2   |   3<br>
    3   |   f<br>
    5   |   e  <br>
  and so on</p>
  
  <p>but
  for PC1 RS232 -> MAX232A -> COPPER WIRE -> MAX232A -> RS232 - PC2
  No error detected and correct value are received.</p>
  
  <p><b>What could be reason for Framing error in Optical link and - what could be the possible solution for the same?</b></p>
