In this version, it’s not possible to open the serial Port on COM1 from the Target Manaeger. I get following error, althouogh the port is by no means in use by another application!! As long a M2M studio is running (with the port unopened), other applications cannot access the port either. After closing M2M studio, other applications (e.g. Hyperterminal, Docklight,… ) can open the port again without a problem.
Error message I get:
Open and load local port COM1 => : The port is already in use by another software. Please close it before trying to open it again.: DevelopperStudio
DevelopperStudio
Open and load physical port COM1 => : The port is already in use by another software. Please close it before trying to open it again.: DevelopperStudio

Hi,
we’ll need some extra information to understand the issue:
What was the previously used version of Developer Studio?
What Windows version are you running?
Concerning your COM1 port, what kind of hardware are you using (native motherboard COM port, extension card COM port, USB/RS232 converter…)?
Did you already experienced troubles with that COM port with other softwares?
The PC is running Windows XP Professional - Service pack 3.
The COM1 port is a native motherboard port and has been /is functioning perfect (I use it daily to interface with serial ports of the devices we develop).
In my opinion, DS uses an extra software layer to address the COM port. Probaly there is something wrong with te settings of this layer.
Please can you just tell us what was the previous version of DS you were using?
Low level serial port handling hasn’t be modified that much for the last versions…
The problem does not occur when I use a new workspace, in stead of using the workspace defined by the old DS.
I guess I just have create a new project in a new workspace andcopy my files into this project?
Mmmm, maybe some incompatibility somewhere if your previous DS version was very old… Just for our information, could try to get the information from the Help > About Developer Studio > Installation Details > Installation History?
However, that’s fine if you can work with a fresh workspace.
The best way to recover your projects is to import them (File > Import > General > Existing projects into workspace): you’ll grab the settings and the source code at the same time.
