OSI Address Lookup using X.500
The VT software is capable of retrieving network ad-
dresses from the X.500 directory. You can use this func-
tionality with or instead of retrieving addresses from a
local repository.
Command Mode
Command mode allows you to execute commands that
can modify the characteristics of the Virtual Terminal as-
sociation with the remote application.
Trace Utility
The VT tracing utility (OSITRACE) is a tool for identify-
ing problems in protocol exchanges between your local
system and any remote system. The utility captures pro-
tocol exchanges and transcribes them into easily read
text.
The tracing utility monitors data exchanges for individual
associations. The utility can trace data originating from
the VT, ACSE, Presentation, and Session components.

Interfaces
FTAM API
The FTAM API supports the OSI standard ISO 8571: In-
formation Processing Systems, Open Systems Intercon-
nection, and File Transfer, Access, and Management.
The FTAM API provides the interface to the FTAM pro-
tocol machine provided in DECnet-Plus. Communica-
tions between the application code and the FTAM pro-
tocol machine are carried out using ASN.1 encoded data
structures. The API supports the following functions:
Abort
Begin-Group
Cancel
Change-Attributes
Create
Close
Data
Data-End
Delete
Deselect
End-Group
Initialize
Open
Read-Attributes
Read
Select
Terminate
Transfer-End

OSI Application Kernel (OSAK) API
The OSAK API provides a direct interface to servcies at
the ACSE and Presentation layer. The OSAK API sup-
ports the following OSI standards for the ACSE layer:
• ISO 8650: Information Processing Systems, Open
Systems Interconnection, Protocol Specification for
the Association Control Service Element
• ISO 8649: Information Processing Systems, Open
Systems Interconnection, Service Definition for the
Association Control Service Element
The OSAK API provides the interface to the ACSE ser-
vices. It provides the following services:
Associate
Release
Abort
Redirect
The redirect service is not an ACSE service. The ser-
vice allows applications to redirect an incoming associ-
ation to another process on the local system.
