As the computing environment evolves, new capabilities and features become possible, and the modem's firmware (internal programming) must be updated to support these changes. The PTC family of Pactor-II/III modems uses advanced state-of-the-art technology that makes it possible for customers to update the internal modem programming, letting you keep your product functionality current with new product being sold. 

As with most computer-related tasks, there are several ways to update the modem firmware, but probably the easiest is to use the firmware update utility screen included in Airmail. To use he Airmail firmware update utility follow these steps:

  1. From the modem models listed below left-click on the link that matches your modem model.
  2. Click on save when you see the screen that asks if you want to run, save, or cancel.
  3. Navigate to your desktop and save the fw38_xxx.exe file to your desktop.
  4. Double click on the fw38_xxx.exe file that you just downloaded and saved. Fw38_xxx.exe is a self-extracting .zip file, and will  unzip itself into a new folder (SCS PTCxxx Firmware V3.8) on your desktop.
  5. Open the newly-created SCS PTCxxx Firmware V3.8 folder and "cut" the file.
  6. Open Windows Explorer (not Internet Explorer).
  7. Navigate to the Airmail program folder on your computer (Hint: Normally the Airmail program is installed in the Program Files folded located on your "C" drive).
  8. Open the Airmail program folder and paste the file into Airmail.
  9. With the modem connected to your computer, turn on the modem and start the Airmail program.
  10. With Airmail's Message Index Screen showing, in the toolbar click on tools, update ptc-ii firmware Airmail will read the firmware version currently installed in your modem and search the Airmail program folder for a newer version.
  11.  When Airmail finds a newer firmware version in the Airmail folder, the start update button will become active (not grayed out).
  12. Click on the start update button, and the rest is automatic. Leave the modem and computer alone for a few minutes while Airmail uploads the new firmware into your modem, and your modem writes the updated firmware into its memory. The whole process may take a minuet or two, so be sure not to disturb the computer or turn off the modem until normal modem behavior has returned.
  13. Remove (delete) these files from your desktop.
  14. Congratulations! You've just updated your modem with the most current firmware version available.
