Try cat > /dev/ttyS?


That will open the port and cause DTR to be raised.

&gt; &gt; Does anyone know of a quick/simple/easy way I can raise the DTR signal 
&gt; &gt; on my serial port?  I'm trying to determine if the port is bad.
&gt; &gt;
&gt; &gt; I can't seem to think of a way to do it with a bash script.  Is there 
&gt; &gt; a command I can send from within Minicom?  Or doe  anyone have a few 
&gt; &gt; lines of C or similar code that could do it?  Is there a gtk app that 
&gt; &gt; will let me toggle serial pins?
&gt; &gt;
&gt; &gt; Anyone have any ideas?
&gt; &gt;
&gt; &gt; Thanks in Advance!

&gt; &gt; P.S.
&gt; &gt; I'm at the console of the box, I'm not connected to a serial tty.
