When issuing the WCSCVxDOpenPort(),
WCSCVxDInitializePort(), or WCSCVxDSetup() an error of
22 (RS232ERR_INVADR) is returned even though the port is
definitely there.
This problem occurs generally if
you are on a Laptop or Desktop with Power Management (e.g., ACPI) enabled. The
workaround for the problem follows.
Solution1:
1.Open the serial port with the windows API(CreateFile() )
2.Use WCSCVxDOpenPort() to open the port.
3.Do your normal programming.
4.Use WCSCVxDUnInitialize() to close port.
5.Close the port with the Windows API.
