- EMBEDDED LAN FILE SHARING SERVICES
- ═════════════════════════════════════════════════════════════════════════
- The Embedded LAN File Server and Embedded LAN redirector allow one target
- running the Embedded DOS operating system to share its file systems with
- other targets on the LAN.
-
- THE FILE SHARING REDIRECTOR
-
- The Embedded LAN Redirector translates requests for remote file I/O into
- streams of protocol on the LAN. This component installs on any 80x86
- Embedded DOS system and intercepts I/O requests associated with network
- drives, routing the requests to designated file servers over the TDI
- Transport Driver Interface. Network drives are created using the NET
- program (a full screen utility), the NET USE command from COMMAND.COM,
- or via INT 21h software interrupt from an application program.
-
- THE FILE SHARING SERVER
-
- The File Server component of Embedded LAN accepts incoming requests
- from its Transport Driver Interface and interprets them as file I/O
- requests. These requests are handled by executing local I/O operations,
- and then returning the results to the requesting node through protocol.
- Each open file or search handle is assigned a separate TDI connection,
- for maximum parallelism; this allows several threads to perform truly
- concurrent I/O to different files simultaneously.
