SYMPTOMS

You connect a Windows Embedded CE 6.0 R3-based device to a terminal server by using the Remote Desktop Protocol (RDP). A serial port on the device is redirected to a serial port on the terminal server. In this situation, an application that uses the redirected serial port on the terminal server does not receive data from the device. Additionally, if the WaitCommEvent function is called on the terminal server, the output of the function indicates that no data is received from a serial device.

CAUSE

This problem occurs because the output buffer length is not updated in the packets that the device sends back to the terminal server. Therefore, the terminal server assumes that no data is sent and does not read data from the serial port.
