One way to tell which COM windows is giving it is to put maple into perpetual bootloader mode ( <a href="http://leaflabs.com/docs/troubleshooting.html#perpetual-bootloader-mode" rel="nofollow">http://leaflabs.com/docs/troubleshooting.html#perpetual-bootloader-mode</a> ) then check the tools-&gt;serial port menu. Note what is listed. Then reset your board and let it exit the bootloader (takes a few seconds, the blinking pattern should stop or change). now check the tools-&gt;serial port menu. the new listing is Maple! </p> http://forums.leaflabs.com/topic.php?id=901#post-5542 Wed, 06 Jul 2011 03:59:40 +0000 nully 5542@http://forums.leaflabs.com/ <p>unplug the usb cable, close the serial monitor and anything else that may be trying to use com9, plug the cable back in. repeat if necessarily. </p> http://forums.leaflabs.com/topic.php?id=901#post-5539 Tue, 05 Jul 2011 22:26:36 +0000 3090103838 5539@http://forums.leaflabs.com/ <p>hello<br /> "serial port ‘com9’already in use.try quit any prigrams that may be using it."<br /> this is found in the serial monitor.How can I solve this problem?I can't use the serial monitor at all.And there is only one option<br /> in the serial port item of com9... </p>
