Dan,<br>   Yes.  I ran it at 9600 baud.  The interface is the serial port on an old desktop PC.<br>I&#39;ll try changing the timing.  That&#39;s a good idea even when I&#39;m using the serial emulator I can&#39;t send a duplicate message very fast.<br>
Thanks,<br>Alan<br><br><div class="gmail_extra"><br><br><div class="gmail_quote">On Fri, Nov 2, 2012 at 3:35 PM, Dan Smith <span dir="ltr">&lt;<a href="mailto:dsmith@danplanet.com" target="_blank">dsmith@danplanet.com</a>&gt;</span> wrote:<br>

What kind of serial port/device are you using? And, I assume the subject<br>
means that your trace of the OEM software indicates 9600 baud?<br>
<br>
You are getting back a NUL byte, which is what the OEM shows (although<br>
granted it doesn&#39;t show the \xfc\xfe).<br>
<br>
The trace shows that it tries the ident string several times in quick<br>
succession, and indeed the radio doesn&#39;t reply on the first. You&#39;re<br>
trying every 1.25 seconds. Perhaps update the timeout to be very short<br>
and nuke the sleep(1)?<br>
