MORE INFORMATION

Steps to Reproduce Behavior

1. Place two laptops supporting irDA and running Windows 98 Second Edition in such a way that the infrared ports are facing each other.



2. Double click on the Infrared Monitor in Control Panel and set the limit speed on the Host to 4 Mbps. Set the limit speed on the Client to any speed above 115.2 Kbps.



3. Double click on My Computer on the Host machine.



4. Double click on the Infrared File Transfer Utility. Choose Send A File.



5. Time the process of transferring the file. It can be observed that the file transfer stops or communication is interrupted at about 70 to 90 % of the file copy process.
