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

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

The Terminal Memory System
One
of
the important features of the Models 763/765 is
their ability to record into and play back information from
the terminal memory. The memory enables you to enter
all your information, review
then transmit the information to other data processing
equipment.

files. The size of the files used

stored in the file. Just as the memory system is composed
of
files, the file itself is composed of records.

file. The records

Creating Files
The files used in memory must be created by the
operator, and each file has four parameters that must be
specified by the operator when creating the file. The four
factors are FILE NAME, FILE FORMAT, FILE SIZE, and
RECORD SIZE. The following paragraphs describe
each parameter

the PLAYBACK
file and only one file can be designated
the

procedure is as
follows:
1.
Press the CMD key to place the terminal

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.

All files in memory start at record 0 and data starts

This means that record 0 is not used to

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.

• If the number entered causes the pointer to move
to a record beyond the
last record in the file, an

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.
If the defined character string is not found before the end
of
the text
is
reached, the terminal will print an ETX,
indicating the end
of
the text, and the record pointer will
point to the
last record in the file.
Multiple
searches for the same text (that is, searching
for
the same character string in more than one record)
may
be accomplished by activating F2 and then using

the
FIELD key (SHIFT and FIELD) which will cause the
most
recently defined character string to be reprinted.

Editing A Record
Once a record is located by using one of the record
locating functions
(F1
through F4), the record will be
printed by the terminal, and the printhead
will remain at
the end
of
the record. The record then may be edited
using the
following guidelines:
• The CHAR and FIELD keys may be used to position
the printheadbelow the character(s) to be
modified. Then you may
"overstrike" existing
characters, or you may add characters to the
existing contents of the record as
long as the
designated maximum record length is not
exceeded.
• The DELETE CHARACTER function
(FS)
may be
used to delete characters within the record.
• The INSERT function may
be
used to insert char-
acters in the record.
• The ENTER key may be used to delete all characters to the right of the printhead,
close the current
record, and access the next record in the
file. (The
SKIP key will perform the same function, but only
on LINE-formatted files.) Using the ENTER key
you can step through an entire file, record by
record, since pressing the ENTER key
also will
cause the next record in the
file to be printed and
made available for editing.
• When editing CONTINUOUS-formatted files, the
SKIP key will generate a special end-of-line
(EOl)
symbol
E3
in the record (This symbol
is
used as
a
line delimiter within the record.)
• Invoking any "record-locating" function
(F1
through F4) while editing a record will terminate
access to that record, store that record in memory,
and activate the selected function.

II
Terminating An Editing Session
Terminating an editing session must be accomplished
by invoking the
STOP function (F8) which causes all
pending editing operations to finish and returns the terminal to the ASR mode.
An
editing session should never
be terminated by pressing the CMD key: inserted or
deleted data may be seriously altered. Terminating
an
editing session purges CONTINUOUS-formatted files
of filler characters by shifting data so as to replace the
purged filler-character space in memory. A message,

Copying Files

Two basic methods are available to copy the data contained in one

in
memory to another.) One way
is
to utilize the COPY command; the other is to use the
ASR mode. The former method offers the added capability
of
copying the contents of a file to the end of the
same
file, facilitating data duplication. The latter method
allows the data to be printed

SECTION IV
TERMINAL COMMUNICATIONS
The communications systems of the Models 7631765
terminals enables the terminals to exchange data with a
variety
of
other data communications equipment. This
section provides information needed by the operator to
use
the terminal with other communications devices.
The
Model 765 has a built-in acoustic coupler which
uses the handset
of
an ordinary telephone to establish a
communications line. The acoustic coupler converts the
terminal digital signals into audible tones. The audible
tones, much like a voice, travel over the telephone lines
to a device that converts the tones back into digital
signals that can be used by a remote device. The acoustic coupler, which contains a modem, is built into the rear
of

Model 763 is capable of operating in several communications c.onfigurations, each of which is described
in this section. The primary use of the Model 763 is
in
hard-wired and external-modem configurations. The
Model 765 is also capable of several communications
configurations, but its primary use is as a
portable
memory terminal using its built-in acoustic coupler as
the means
of
communications.
When a modem (also called a data set) is used with
either terminal, a modem is necessary at both ends of
telephone lines. Several types of modems are avail-
the
able on the commercial market, and it is very important
that the same types of modems are used at both ends. If

December 1979
These instructions assume familiarity with operation of
the Model 763 or 765 memory terminal and assume
adequate knowledge of RUN files and other programming features of the terminal.
Character Mapping is a method to permit real-time
substitution of certain characters received or transmit-
ted by the Models 763/765 memory terminals. The
primary use of character mapping is found

Although the entire ASCII set can be mapped for both
transmitted and received data, throughput is reduced
with each mapped character. For example, if only one
character is mapped, the worst-case delay is 40 microseconds; for
milliseconds (the average delay is 1 to 2 milliseconds).
At 300 baud and 1200 baud, normal character mapping

the printout as explained below.
Example
Figure 2, Part 1 is a sample terminal printout of a conversational session with a host system. It shows how a
character mapping file may be defined by examining the
differing character definitions between the host and the
Model 7631765. In the example, the 00010, 00020,
00030
acters were transmitted by the terminal operator to the
host system. Figure 2, Part 2 is an editor printout of the
data recorded. Note that a line feed, a DC1, and DC3
also were sent by the host.
