I finally figured out that it was my computer mouse using the port. Thanks so much for your help!!!

A quick and easy way to regain access for programming would be to restart your computer. Otherwise, you must find out what is using the COM port and cause that program to release it. Out of curiousity, are you using LabVIEW to communicate with your motes??? If so, make sure that you include the subvi that closes the COM port in your application. I suppose that goes for any software you are using to communicate with the motes though.</DIV><DIV> </DIV><DIV>Regards,</DIV><DIV>Matt<BR></DIV><FONT color=#990099>[EMAIL PROTECTED] wrote: -----<BR><BR></FONT><blockquote style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px">To: [email protected]<BR>From: abensong <[EMAIL PROTECTED]><BR>Sent by: [EMAIL PROTECTED]<BR>Date: 06/15/2006 09:41AM<BR>Subject: [Tinyos-help] could not open port: (5, 'CreateFile', 'Access is denied.')<BR><BR><FONT face="Default Monospace,Courier New,Courier,monospace" size=2 >When trying to install a program on my TelosB mote, I get the following error: <BR>could not open port: (5, 'CreateFile', 'Access is denied.')
