/***********************************************************************
* CommConfigDialogA (KERNEL32.@)
*
* Raises a dialog that allows the user to configure a comm port.
* Fills the COMMCONFIG struct with information specified by the user.
* This function should call a similar routine in the COMM driver...
*
* RETURNS
*
* TRUE on success, FALSE on failure
* If successful, the lpCommConfig structure will contain a new
* configuration for the comm port, as specified by the user.
*
* BUGS
* The library with the CommConfigDialog code is never unloaded.
* Perhaps this should be done when the comm port is closed?
