Open ports with Windows Mobile 6

[Julián Sanz García]

Hi,

I am developping a demo application that only open a port with CreateFile
method and read port data with ReadFile method.
When i open the com port, a read thread start. This thread has a while loop
which has the ReadFile call. My application fails when this loop try to make
the 5 iteration to ReadFile method call.
I think the exception throws is an access violation exception (0xc0000005)

Can anybody help me?

Thanks

The easiest way to read from a serial port in a managed code app is to use
the Ports.IO.Serial class. Certainly you can use CreateFile, ReadFile, etc.,
but the Serial class has already done the work including managing the worker
thread.

Not without seeing code we can't.

Is this serial port code? If so, then you should use the built-in
System.IO.Ports class -- there can be reasons to write your own code, but
this would be unusual. If not serial port code, then you will have to
provide more details.
