MORE INFORMATION ================ COMTI TCP/IP security information is sent in the following format: +------------------------------------+ | Byte | Data | +------------------------------------+ | 1 - 4 | Transaction Program Name | +------------------------------------+ | 5 | '0x6B' (Comma Separator) | +------------------------------------+ | 6 - 13 | User ID | +------------------------------------+ | 14 - 21 | Password | +------------------------------------+ | 22 - 40 | Program Data | +------------------------------------+ Microsoft has updated COMTI to support the default IBM-supplied security exit, EZACICSE. After you apply the update and add the specified registry entry, COMTI TCP/IP security information that is supported by EZACICSE is sent in the following format: +------------------------------------+ | Byte | Data | +------------------------------------+ | 1 - 4 | Transaction Program Name | +------------------------------------+ | 5 | '0x6B' (Comma Separator) | +------------------------------------+ | 6 | '0x01' | +------------------------------------+ | 7 - 14 | Password | +------------------------------------+ | 15 - 22 | User ID | +------------------------------------+ | 23 - 40 | Program Data | +------------------------------------+ WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. This update requires that you add a registry key so that COMTI can send the TCP/IP security information using the IBM format for EZACICSE. To add the registry key, follow these steps: 1. Start Registry Editor. 2. Locate and then click the following key in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cedar\Defaults 3. On the Edit menu, click Add Value, and then add the following registry value: Value name: UseIBMTCPSecurityExit Data type: REG_SZ Value data: TRUE NOTE: The actual data value is not checked, but you must enter a data value. 4. Quit Registry Editor.
