Installation

To install DOS EHLLAPI support for Personal Communications do the following:
  1. Select the Emulator Utilities folder from the Utilities folder in the IBM Personal Communications folder.
  2. Select DOS EHLLAPI application from the Emulator Utilities folder.
  3. Select the check box of the DOS MODE EHLLAPI to enable DOS EHLLAPI support.
  4. Enter the major DOS version for which your DOS EHLLAPI applications are written. (For example, 2 for DOS Emulator Version 2.x).
  5. Select OK to enable changes.
  6. Shut down the workstation and restart it again.
This procedure adds the following statement in config.nt. 
device=%SystemRoot%\system32\drivers\hlldrvr.com
Note: DOS EHLLAPI applications assert interrupt X'7F' to request EHLLAPI services. Any other proprietary DOS application using interrupt X'7F' will not work with DOS EHLLAPI enabled and vice-versa.
