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.
