SYMPTOMS
When you install a serial smart card reader on a multi-serial port device, the reader may not function. However, the reader works correctly when it is connected to a serial port on the motherboard.



CAUSE
This behavior is usually caused by a multi-serial port device not supporting a Received Line Signal Detector (RLSD) line, which the smart card reader may use to detect smart card insertions and removals.

To verify this, plug the reader directly into the serial port on the computer.



RESOLUTION
If plugging the reader directly into the serial port on the computer works, either use this configuration or upgrade to a newer multi-port device or reader.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
You may also want to check with the manufacturer of the multi-port device or smart card reader for any other possible workarounds.
