Unsigned Ether-Serial Link drivers & Windows Verifier in Win 2000 & XP
Ether-Serial Link Driver Mode interaction with Microsoft's "Verifier" in Windows 2000/XP

General: This note applies to Ether-Serial Link™ serial ports operating in DRIVER mode.

EVENT: Interaction between the Ether-Serial Link™ and Microsoft's driver verifier software may cause a blue screen system crash. This event will be encountered when accessing or sending data to a serial port enumerated under an Ether-Serial Link™.

COMMENTS: The Windows 2000/XP Verifier utility may have settings enabled to verify signed/unsigned drivers. The serial drivers used by the Ether-Serial Link™ are compatible with Windows 2000/XP, but are not “signed” by Microsoft. Therefore, to prevent system crashes, disable the Verifier settings, and re-boot the PC for the new settings take effect.

RECOMMENDED CORRECTIVE ACTION: Update your drivers to the newest set, which are signed by Microsoft.

CORRECTIVE ACTION FOR THOSE CONTINUING TO USE OLD DRIVERS: Disable the Verifier settings as follows:

1. Go to START. In the "Run..." dialog, enter “verifier” and select "OK". The Verifier application will appear with a selection of options.

2. Disable settings, and exit from the Verifier. You can confirm on-screen that the settings have been disabled. HOWEVER, you MUST reboot the PC for the new settings to take effect.

3. Reboot the system, then re-check that the Verifier settings have been disabled.
