title: Cannot send character with minicom
body: <p>I'm using minicom to connect through a serial link to a target (UART link of a sparc processor).
  With gtkterm or cutecom, I can connect, read and send characters. The only issue with them is that they both insert empty lines after each LF character, and :
  -gtkterm cannot record output to a file
  -cutecom does not "flush" after recording output to a file (it gets delayed, and flushed only after every 16k bunch of data)</p>
  
  <p>Minicom, which is console based, would solve these problems (and it does not insert empty lines...), but I still cannot send any character with it, and don't understand why!
  When I press a key (for example, "0" + Return), is is written (if I enable local echoing), but nothing happens (while it works with gtkterm and cuteterm!!).
  In my program, I read using the following :</p>
  
  <pre><code>`r = scanf("%d", &amp;option);`
  </code></pre>
  
  <p>Using a debugger, I see that the program never goes past this line...</p>
  
  <p>Has anybody any idea?</p>
