title: Communication with RS232 port in Java
body: <p>I'm trying to solve one problem with the "communication with RS232" port using Java, because my skills on C are not so great!</p>
  
  <p><strong>The problem:</strong></p>
  
  <p>I have a dynamometer (if you care what is the machine that I'm using) that send the data to my pc through RS232. The main idea is that when I send the ASCII code 'S' to it, the dynamometer should return me -</p>
  
  <p>18 bytes as follows: 0,1,2,3,4 - the messured force F; 5,6,7,8,9 - Fmax; 10,11,12,13,14 - the messured speed dF/dT and bytes 15,16,17 - status (0/1 for each -  MaxHold, Nulled, Overload). All the bytes are standard ASCII strings.</p>
  
  <p>So my problem is that I will make the rest of the code, the loops for sending the 'S', the Null command to the machine at the beginning... I have no problems to safe this info into a file for example .txt either. </p>
  
  <p><strong>My problem is</strong> that I cant understand and I cant find maybe an already done and known method for simple sending/receiving commands or information through this RS232. </p>
  
  <p>As far as I saw... I will have to use the class javax.comm that is not supported since... ages and the other way is to use rxtx libs that I cant find in google because it says to me that their webpage is somehow... not working. I'm afraid that there won't be any good doc for this lib and I will fail with the use whether I get it or not.</p>
  
  <p>I know that my problem is not so easy maybe but this is part from my final educational exam and I really need help. I will appreciate it BIG TIME!</p>
  
  <p>Thanks a lot from now on to the ppl that will try to help me!</p>
  
  <p>PS: Sorry for my bad grammar.</p>
