8.This should allow you to connect to the unit. The status area at the bottom left corner of the HyperTerminal window will display Connected and the amount of time you have been connected.
9.Click the Transfer tab at the top of the HyperTerminal window, then select Send Text File.
10.In the Send Text File window, specify the location of the firmware text file, then click Open. Several dots will appear across the HyperTerminal screen, indicating that it is checking for errors. Then it will begin downloading the file to the unit.
11.When the download is complete, a message appears and the status area changes to Disconnected. At this point, you may close the HyperTerminal program by clicking on the File menu, then on Exit.
If you have not saved the connection created in Step 5, a prompt message will ask whether you wish to do so.
