INTRODUCTION

The Texas Instruments Silent 700* Model 763 memory
send/receive data terminal and the Model 765 portable
memory data terminal are designed for easy, versatile

storage and communication of data. The memory

in
both models is implemented using a revolutionary new
electromagnetic
by Texas Instruments. The Model

bubble

memory device manufactured

763 is a compact,

table-top data terminal designed for office use. The
Model

765 is a portable unit furnished with

an

attache­case-like cover to make it useful wherever a standard
telephone and an electrical outlet are available. Both
models are capable of sending

and

receiving

information over long or short distances with equal
ease.

A memory data terminal, usually referred to as an auto-

matic send/receive

(ASR) data terminal,

is

equipped to

store data in its memory (magnetic bubble, magnetic

Data Terminal Communications

A data terminal generates codes. The Models 763/765
memory data terminals use the American Standard
Code for Information Interchange (ASCII), commonly
called

"as-key",
codes can

devices such as data terminals, computers, video ter­minals, and data loggers.

The code system consists of various combinations of
ones and zeros corresponding to numbers, alphabet
characters, control characters, or symbols. Combina-

763/765 terminals also understand,

ASCII or C.C.I.T.T. codes from other

tape, paper tape, diskettes, etc.) from its built-in key­board or from a communications line (usually a tele­phone line). The stored data is then available for editing

(corrections, changes, deletions, additions to the re­corded text), printing, and for transmission to other de­vices at much higher speeds than manual keyboard

How are the digital signals transmitted from one device
to another?

If the distance is about 15 meters (50 feet)

or
less, cables are used to interconnect the devices and
the devices are referred to as hard wired together

(directly cabled). For example, when

connected to a computer for use

whatever it may be doing to await your command,
so be careful not to press the CMD key accident­ally.

control the designated PLAYBACK and

the PLAYBACK

file and only one file can be designated

the

designate one of the

a file by the name

of

procedure is as

follows:

1.

Press the CMD key to place the terminal

in

the COMMAND mode.

2.

Type CHANGE

3.

Press the SKIP key to execute the com-

Once the three steps are completed, all functions

on the DATA-1 file. The same is true with the

can be either the same files

or

different files.

ASR function keys are activated by pressing and hold­ing the FCTN key on the lower right corner of the key­board and then pressing the appropriate number key
along the top row of the keyboard. For example, to
activate the

REWIND PLAYBACK function, press and

hold the FCTN key and press the 5 key.
The

For example, if DATA-1 is both the PLAYBACK and

be rewound.

If the files had different file names, the

Function

Keys. The operation

and

terminal responses associated with each function

key are described in this section. For additional

details

concerning the editing functions, see Section I of the

Systems Manual.

F1 -INDEX

Function.

The INDEX function provides
access to records during file editing. Records are ac­cessed

relative to a record pOinter which "points" to the

record in the

file which was accessed. Upon entry into

the

EDIT mode, the record pointer will point immediately

above the first record in the file.

Activating the INDEX function causes the terminal to
perform a carriage return,

followed by a line feed and

printing

of

the INDEX prompt symbol + . A signed

(+

or

- ) number from 0 to 999 may then be typed to specify

the

location of the desired record relative to the record

currently pointed to. If no sign

(+

or

-)

is specified, the
teminal assumes the number is positive. The entered
number

may be corrected using the CHAR key.

-

Once the desired number is entered, the entry is termi­nated by pressing the

SKIP key. The terminal will then
add (subtract if a negative sign was entered) the number
to (from) the current record

location and go to the

new

record location. When the requested location is

reached, the

terminal will print the record, making it

available for editing.

For

example, if the current location is the tenth record in

a

file, typing a

-6

will cause the INDEX function to

relocate

the

record "pOinter"

to

the fourth record in the

file.

If

the SKIP key is pressed before a number is entered, a

1 is assumed by the terminal. As a result, the terminal
will then point to the next record in the file. Typing a zero
will keep the

pOinter at the current record location. Acti-

vating any of the other

"record locating" function keys

(F1

- F4),

or

the INSERT function key, will terminate

the

INDEX function and will initiate the new function.

In summary:

•

A signed number followed by pressing the SKIP
key will move the editing record pointer that num­ber

of

records and direction

(+

or

-).

For exam­pie, if you want to review the text six records
before the current record in the

file, type a

-6.

If no

number is entered, a

+1

is assumed.

19

•

Section II

All files in memory start at record 0 and data starts
at record

1.

This means that record 0 is not used to

store data, but

simply. is a record which comes

before the first data record

in

the file. The concept

of record

0 is necessary to insert data before the

first record in the

file.

•

The editing record pointer cannot go to a negative
record

location (Le., before the first record in the

file). For example,

ifthe

record pointer is located at

the fifth record in the file and you enter

-6,

the

record pointer

would not

"go

negative", but would

point

to

0, just before the first record

of

the file.

• If the number entered causes the pointer to move
to a record beyond the

last record in the file, an

ETX (end of text)

symbol will be printed and the

record pointer will point to the

last existing record

in the

file.

F2

- FIND

Function.

The FIND function is used to
locate a memory record which contains a defined char­acter string (a group of characters). Upon activating F2,
the

terminal will print the FIND prompt symbol
( (:. ) in the left margin. A character string of up to 30
characters may then be typed. While typing the char-

~

-

acter string, the CHAR and FIELD keys may be used to

- -

make corrections.

After entry

of

the character string, press the SKIP key.

The

terminal then will forward space once and print the
FIND symbol and begin a search for the character string
in the

file contents. The search will start at the current

record location plus one record. When the desired

record is

located, the terminal will print the record and

the record pointer will point to this record. The record

then is

available for editing.
