title: SIM300 send sms in Mikroc using PIC16f
body: <p>I have been trying to send SMS using an SIM300 module. Though module is working fine when tried using Hyper Terminal, but i am not able to send the SMS using PIC.</p>
  
  <p>Below is the code that i tried (LCD also included (Lcd is working fine)):</p>
