In addition to the standard drivers, the VME supports the following OSFI drivers defined in the dm,hosts, file.
| Driver | Description |
|---|---|
| OSFI Windows Driver | Access to the underlying host file system. This driver and some derivatives allow access to Windows. |
| OSFI Remote Pick Files | Access to remote D3 files through TCP/IP. This driver allows access to a remote D3 system. See the D3 Reference Manual for more information. |
| FSI Driver | Access to the distributed File System Interface. |
This driver allows access to the underlying Windows file system with the following conventions:
D3 file is represented by a directory, and the directory must exist.
D3 item is a Windows file.
Dictionary of a D3 file is represented by a subdirectory $DICT.
Examples of Windows driver names are:
| Driver Name | Description |
|---|---|
| NT | Used for text records in which a line is terminated by a line feed. When copied into D3, the line feed is replaced by an attribute mark. |
| DOS | Used for text records in which a line is terminated by a carriage return / line feed. When copied into D3, the sequence carriage return / line feed is replaced by an attribute mark. Tabulation are also replaced by 4 spaces, and vice versa. |
| NT_BIN | Used for binary records or data which must not be translated
in any way. Warning: This driver should not be used to
read items using the BASIC READ statement.
|
Examples of valid Windows OSFI file names are:
| OSFI File Name | Directory | Description |
|---|---|---|
| NT | /temp | Directory /temp on the current drive. |
| DOS | D:/temp | Directory /temp on the drive D:. |
The options in the host item are identical to the options of the UNIX driver with the following addition:
Lxwhere x is a one letter code representing an MS-DOS drive letter. This option eliminates the need to specify an MS-DOS letter.
The entries A, B, C, and D in the host file are shortcuts to the MS-DOS drives A:, B:, C:, and D:. For example, it is possible to refer to the file A:/Docs, as a D3 file.
