How do I access a serial port under Windows CE? The Visual C++ code
accesses the comm port under Windows 2000.  When the code is ported
to the Windows CE emulator, it compiles and links but doesn't connect.
 Instead the connecting method "FileConnect", returns
"INVALID_HANDLE_VALUE".

The method used to connect to the serial port is NOT "FileConnect" but
rather "CreateFile" - sorry for the confusion/

It could be easier to answer if you provided some error code or exact
statement and parameters you passed to CreateFile.

Never the less you can check:

1) are serial ports defined (enabled) on your emulator
2) maybe some other process is using serial port in question
3) serial port name must end with ':' on WinCE e.g. "com1:" and not
"com1" which works on 'regular' windows.

Hope some of this helps.

I am having a similar problem.  I am trying to write an application
that will communicate with a serial peripheral via the serial port and
I can open the port just fine, but when I send data over it, I get the
ActiveSync connect string interspersed with my data.  How do I disable
ActiveSync while I am trying to use the port?

Thanks!
