Task-to-Task Communications
User programs written in Microsoft's MACRO Assembler or the C language
can exchange messages with other network user programs. A simple set
of functions is provided by the transparent Task-to-Task interface (TTT),
which allows communication and exchange of data with a remote network
program through a limited set of DOS calls (for example, OPEN, CLOSE,
READ, and WRITE).
Transparent File Access (TFA) is a utility that allows access to re-
mote DECnet systems through supported DOS function calls such as READ,
WRITE, OPEN, CLOSE, SUBMIT, DIRECTORY, and DELETE.
Note: The Task-to-Task interface (TTT) and the Transparent File Access
(TFA) utility are currently not supported under Microsoft Windows, Ver-
sion 3.0/3.1. TTT will be discontinued concurrent with the next re-
lease of this product. Digital recommends that applications utilize
the socket library for this purpose.
User program-to-user program capabilities (nontransparent) are pos-
sible in C or MACRO Assembly through a library of special network sub-
routine calls. This gives the network programmer access to the com-
plete set of DECnet functions. The user may need to adapt the PATHWORKS
for DOS C language subroutines to the specific C compiler being used.
Small, medium, and large size memory models are supported.
The PATHWORKS for DOS license grants a royalty-free, non-exclusive li-
cense to use Digital's source code located only in the subdirectory
\PCSAV41\DECNET\SOURCE to create binaries that a user may then copy
and merge with user's software for distribution to its customers.
A program written for the DOS client using the programming libraries
can be identified as a network object and invoked through the Job Spawner
utility.
The Job Spawner is a utility that allows a personal computer to act
as a server for performing multiple service functions. When the Job
Spawner is enabled (it must be the only utility running), it listens
for connect requests from other nodes and initiates the program that
