SYMPTOMS

When you install the Attachmate SDLC card and the Attachmate Advanced SDLC card using the link support included in SNA Server 2.0, 2.1, 2.11, or 2.11 Service Pack 1, the link support does not function properly for computers that have an ISA/PCI bus configuration. The problem may manifest itself in the following ways:
  • Link Service will start, but the connection defined for it in SNA Server Admin will not shift from Inactive.
  • Link Service will start, the connection will shift to a Pending state, but if a Level 2 trace is taken on the Link Service, the trace will show no frames sent or received.
  • Link Service will start, but modem does not dial or respond to dial commands. The modem status lights will not show any change.
  • Link Service will not start.

CAUSE

The above symptoms may be due to an incompatible INF file. If the Link Service was installed with an improper INF file, the card name will not show in the drop down box labeled Card Type of the Link Service Setup dialog box.

WORKAROUND

Attachmate provides replacement driver and INF files on their Web site:

http://www.attachmate.com

Use your Web browser to connect to this site. Go to the Support section, select the File Library section, select the Hardware folder, and download the appropriate file for your specific Attachmate SDLC card.

The files are self extracting executables. After you extract the files, follow the steps below to replace the INF file on your SNA Server (if you are using a version previous to 2.11, you may also need newer drivers):
  1. Remove the link service using SNA Server Setup.
  2. Run File Manager.
  3. Search the SNA root directory and all subdirectories for a file named Advsdlc.inf (for the Attachmate Advanced SDLC card), or Atmsdlc.inf (for the Attachmate SDLC card).
  4. Replace the file with the corresponding file from the download from the Attachmate gopher site.
  5. Add the Link Service again. The name of the card should appear in the pull down box at this time.

MORE INFORMATION

You can detect the problem by using the following steps:
  1. Ensure that the card is installed correctly by verifying that no IRQ, DMA (in the case of the Attachmate SDLC card), I/O address, or Shared Memory Address (in the case of the Attachmate Advanced SDLC card) conflicts exist. Also, verify that Plug and Play is disabled, as well as any other settings that may conflict with Microsoft Windows NT.
  2. Run the SNA Server Setup program.
  3. Click the Continue button, and then click the Links button.
  4. If the Attachmate link service has been installed already, click the Attachmate link service, and then click the Configure button. Otherwise select the Add... button, and select the appropriate Attachmate SDLC link service. Ensure that the SNA Server media is accessible in case the Setup program asks for the installation path.
  5. After you configure the card specific parameters, click Continue until you reach the Link Service Setup window.
  6. Select the Card Type list. If no card appears on the list, you probably have the incorrect INF file.
