When you attempt the subject data transfer, the IR connection is refused by Windows 98, and you receive an error similar to:
The transfer failed. An error occurred while Wireless Link was connecting to the other device. No connection could be made because the target machine actively refused it.
This problem occurs because Windows 98 does not release some resources during the data transfer, causing Windows 98 to refuse the IR connection.
To workaround this problem, disconnect and then re-connect the IR connection until it succeeds.
