NETRJT -- Remote Job Service Protocol for TIPS
TIP's have very limited processing capability; their function is
mainly limited to interfacing printer-keyboard devices to the Network
using TELNET protocol. It will also be possible to have a tape drive
on a TIP, using a subset of the count form of DTP (see RFC #264).
However, TIP's cannot and will not support either DTP or FTP (see RFC
#265) in general. Therefore, TIP users are excluded from using any
existing remote job entry protocol (e.g. CCN's NETRJS - see RFC #189).
It appears, however, that it may be feasible in the future to use
TIP's for remote job entry in one or more of the following three ways:
(a) Attach local card readers, line printers, and card punches
directly to TIP ports. These devices would use a TELNET-like*
format and frame their characters with Start/Stop bits. BBN
can now supply a suitable 200 LPM printer, and is searching for
suitable readers and punches.
(b) Connect a remote batch terminal to a full-duplex TIP port via
a communication line. BBN is looking into this.
(c) Use the tape drive, and do card-to-tape and/or tape-to-print
on another computer.
BBN hopes to make case (b) look exactly like (a) to the server host.
That is, the remote batch terminal will send to and receive from the
server in a TELNET-like format*; the printer, card reader, punch, and
operator console connections will all use different sockets but one
hardware port at the TIP, which will map multiple sockets into the one
NOTE: By "TELNET-like format", we mean: (a) _CR_LF_ used to delimit
logical records (lines or cards), and (b) the ASCII or EBCDIC
format effector control characters used for carriage control
in the printer stream. It does _not_ necessarily imply ASCII

This document describes NETRJT, a modification of CCN's NETRJS
protocol specifically to provide remote job entry service to TIP's
using one of the methods (a), (b), or (c). NETRJT follows the general
model of NETRJS: use TELNET protocol over a primary or "operator"
connection pair, and open simplex secondary connections for data
transfer of job stream input and output. (We also considered the
possibility of using the Divert Output mechanism of the TIP for
sending remote job output over the operator connection, and an
analogous mechanism for input. However, in discussion with Alex
McKenzie, it was agreed that sharing the operato...
