TELNET Data Entry Terminal Option
DODIIS Implementation
Status of this Memo
This RFC suggests a proposed protocol on the TELNET Data Entry
Terminal (DET) Option - DODIIS Implementation for the Internet
community. It is intended that this specification be compatible with
the specification of DET Option in RFC-732. Discussion and
suggestions for improvements are encouraged. Distribution of this
memo is unlimited.
Introduction
In the early 1980s, the Defense Intelligence Agency (DIA) undertook
the tasks of developing a TELNET capability to access full screen
applications across a packet switching network. This effort was
successful by implementing Data Entry Terminal (DET) options within
the TELNET protocol based on RFC 732. These DET options have been
implemented on IAS, MVS, OS86 and UNIX operating systems. DET
options are being developed for VM and VMS operating systems.
The Department of Defense Intelligence Information System (DODIIS) is
a confederation of heterogeneous computer systems and remote
terminals utilizing the Defense Data Network (DDN) as the
communications backbone (namely the SCINET/DSNET-3).
Although the reason for implementing a DET option specification was
based upon data base application interfaces, the use of a full screen
TELNET provides a method to achieve higher efficiency on the network.
Most terminal to host applications on the ARPANET are character echo
TELNETs. This is both costly in time and network utilization, since
one character pressed on the keyboard generates a datagram composed
of TCP/IP headers plus the character sent to the host and the host
echoes back a similar datagram. In the DODIIS community, programmers
are highly encouraged to implement full screen applications; line at
a time is acceptable; and character remote echo mode is discouraged.
This RFC in its final form will be implemented on SCINET. During the
interim period, the "DODIIS TELNET Network Virtual Data Entry
Terminal (NVDET) Option Specification", DIA, April 1983, will be
implemented.
