             NETRJT -- Remote Job Service Protocol for TIPS
             ----------------------------------------------

A.  INTRODUCTION
    ------------

 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
port.

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
       character codes.
