USER/SERVER SITE PROTOCOL

NETWORK HOST QUESTIONNAIRE

The answer to a number of questions about the characteristics

and operation of Network HOSTS will be useful to implementers of some

early versions of TELNET, and/or to the USER/SERVER SITE PROTOCOL

Committee in their consideration of a full TELNET PROTOCOL

specification.

Questions of current interest are covered on the attached

questionnaire. The Technical Liaison contact at each HOST site is asked

to review these questions and fill in the answers as soon as convenient

after receipt.

One of the members of the committee listed below will contact

each HOST site by telephone in the next few days to record the answers.

Committee members include:

         Bob Long                   SDC

         John Melvin                SRI/ARC

         Ed Meyer                   MIT/MAC

         Tom O'Sullivan             RDS

Results of the questionnaire will be tabulated and distributed

as an RFC.

For TELNET Consideration

Installation __________________________ Prepared By _______________

System** _____________________________ Date _____________________

1.) Does system operate on keyboard terminal input on one

character at a time (e.g. searching for a special
character other than end of line), or does it accumulate a line at a time and operate on the line when a
special character is entered, e.g. Carriage Return (CR)?

[ ] Line at time

[ ] Character at time

[ ] Both (Explain) __________________________________

_____________________________________________________________

2.) What maximum buffer size does your system provide for

input of a physical line from a keyboard terminal, and for output to a terminal, printer, or screen?

Input______Char

Output_____Char

Remarks: ____________________________________________________

_____________________________________________________________

=================

 * If there is insufficient space on the questionnaire, continue
   answers on back of page.

** Fill out separate questionnaire for each HOST to be directly

interfaced to an IMP.

[Page 2]

3.) Describe the effect in your system of use of the following

keying conventions. Indicate how implemented, i.e. is there a hardware interrupt? Does the terminal respond? How? What is sent into system as data, what is echoed, etc. If the key(s) are not available, so indicate (as may be the case for Newline for some systems, line feed for 2741's, etc.). If available but has no meaning, so indicate.

       Key Strokes        Implementation           System Action

          CR       __________________________   __________________

          LF       __________________________   __________________

          NL       __________________________   __________________

        CR,LF      __________________________   __________________

Terminal Type = __________________________

If appropriate, enter data for other terminal types on the back of this page.

4.) What special character or characters are used in your

system to awaken some process during the entry of data from a terminal (e.g. control C for some systems, break on others, etc.)?

       Character(s)                 Operation

       ___________    ___________________________________________

       ___________    ___________________________________________

       ___________    ___________________________________________

       ___________    ___________________________________________

[Page 3]

5.) List the types of keyboard terminals and codes supported

by your system.

__________________________________________________________

6.) What internal code(s) is used in your system to represent

character sets? If not ASCII nor EBCDIC, attach a copy of the code.

__________________________________________________________

7.) For each terminal type do you support it in:

Half Duplex (Pure) _______________________________________

Half Duplex (with Break or Attention) ____________________

Half Duplex (Break & Reverse Break) ______________________

Full Duplex (without echo) _______________________________

Full Duplex (with echo) __________________________________

8.) For optional echo systems, at initial connect time

is the terminal assumed to require an echo?

[ ] Yes

[ ] No

[Page 4]

9.) Does your system perform error detection (e.g. parity

check) on terminal input and, if so, is this a hardware or software check?

_____________________________________________________________

10.) Does your system support punched paper tape input? If so,

what sort of end of line sequence is used?
