We should have checked. In the meantime, here's a workaround using PuTTY:</p> <p>1) Download PuTTY: <a href="http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html" rel="nofollow">http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html</a><br /> 2) Run putty.exe<br /> 3) There will be a radio menu titled "Connection Type". Choose "Serial", then pick the COM port corresponding to your Maple, and you should be all set. </p> http://forums.leaflabs.com/topic.php?id=657#post-3724 Thu, 24 Feb 2011 08:04:10 +0000 crenn 3724@http://forums.leaflabs.com/ <p>The thing that interests me is the behaviour changed, when using the slightly different function, to what I would expect it to be. However, I'll go and check out this shortly and see what happens.</p> <p>Also, I strongly believe that Windows 7 (The only OS I've been using for this project, so far) has no longer got a serial monitor built-in. However, I do have 3rd party programs that I use (although usually only used with either different serial hardware or to complete a serial connection with a bluetooth module). </p> http://forums.leaflabs.com/topic.php?id=657#post-3718 Wed, 23 Feb 2011 21:58:08 +0000 mbolivar 3718@http://forums.leaflabs.com/ <p>(And sorry for not being more clear about what to expect!) </p> http://forums.leaflabs.com/topic.php?id=657#post-3717 Wed, 23 Feb 2011 21:45:20 +0000 mbolivar 3717@http://forums.leaflabs.com/ <p>Hi Stephen,</p> <p>Yes, as I mentioned when I posted the snapshot, there appears to be a regression in the IDE's built-in serial monitor:</p> <p><a href="http://forums.leaflabs.com/topic.php?id=651" rel="nofollow">http://forums.leaflabs.com/topic.php?id=651</a></p> <blockquote><p> There've been some issues lately with the built-in serial monitor; if you get bad behavior, try using something like PuTTY, HyperTerminal, screen, or minicom. Working on fixing this as well. </p></blockquote> <p>The behavior is the one you discovered: If you try to echo back some bytes, you'll appear to get copies of the first byte you sent.</p> <p>We've tested it out on other terminal programs (e.g. screen, minicom) and everything works fine. This behavior is not a problem with the SerialUSB implementation. We're going to get this issue ironed out before the next release, but for now, since every OS comes with a serial monitor built-in, we recommend not using the IDE's serial monitor as a workaround. </p> <p>Thanks for the report! </p> http://forums.leaflabs.com/topic.php?id=657#post-3695 Mon, 21 Feb 2011 09:40:51 +0000 crenn 3695@http://forums.leaflabs.com/ <p>It was a problem with the code I posted above due to the code not working how I was expecting it to work. </p> http://forums.leaflabs.com/topic.php?id=657#post-3688 Sun, 20 Feb 2011 11:12:48 +0000 gbulmer 3688@http://forums.leaflabs.com/ <p>I don't see any null character in your post</p> <p>try <code>&#39;\O&#39;</code> (used the letter O, instead of 0, yes, rubbish, but better than nothing) </p>
