Installing the BTRBOX Requester
PSQL v12 supports DOS Btrieve applications with the BTRBOX requester for Windows platforms. Use this Requester for legacy DOS applications.
A separate installation is no longer needed for the DOS Requester. The DOS Requester is automatically installed during a complete PSQL v12 engine installation. In the case of a Custom installation, you must select the Btrieve DOS optional feature in the PSQL Access Methods group to install the DOS Requester.
Note:
Clients using the DOS operating system will have only transactional access to the data files. No relational access is available for this platform.
Win32 DOS Box Support
BTRBOX allows a DOS application to run in a DOS box on a Windows workstation. This enables direct communication to the Windows 32-bit workstation components rather than to the database engine. This configuration can be used with either a local PSQL v12 Workgroup engine, or a remote PSQL v12 server engine. The TCP/IP or SPX protocol supported for client/server access depends on the configuration of the Windows 32-bit components.
DOS applications are not supported on 64-bit Windows platforms. Therefore, BTRBOX is not supported on 64-bit Windows platforms.
Note: Clients using the DOS operating system will have only transactional access to the data files. No relational access is available for this platform.
