IBM 3790 Communications System

~ the host computer. When equipped with the Data Link Adapters, up to 80 additional remote devices can be con-trolled. As an alternative, the data can be transmitted to the host computer as it is edited (inquiry session), without being stored on diskettes. Magnetic tape can also provide input to the system.

All operations are executed under program control. The 3790 receives its operating software from the host computer via the communications facility. Following receipt of the software, the 3790 operates independently of the host system.

All 3790 programs are compiled and can be tested on the host System/370 computer prior to use on the remote 3790. The application programs are prepared by the user via a System/370 assembler and statements defmed in an IBM-supplied macro library. Program debugging is performed with the aid of a utility package, Program Validation Service (PVS), on the host computer. PVS also formats 3790 programs for storage at the host computer and later trans-mission to the 3790. Subsystem Support Services (SSS), another utility, controls 3790 program libraries at the host site and controls the transmission of 3790 programs from the host computer to the 3790.

COMPONENTS

3793 KEYBOARD-PRINTER: The 3793 is a modified Selectric II typewriter terminal oriented toward the functions of the 3790 system. It contains a serial impact printer that prints full characters at speeds up to 15.5 characters per second; input symbols total 88. Vertical forms movement and print positioning can be performed under program control.

The printer accommodates friction-fed or pin-fed (optional) continuous forms up to 15.5 inches wide; the printing width is 13 inches. Horizontal spacing is 10 to 12 characters per inch;

vertical spacing is 6 lines per inch.

The typewriter-style EBCDIC keyboard includes operator guidance lights and switches.

3277 D1SPLA Y STATION: The 3277 is a CRT display unit with a 14-inch (diagonal measurement) CRT screen. The display screen arrangement is dependent on the model, as shown below.

3277 Display: Model I Model 2

Characters/ display: 480 1920

Lines/display: 12 24

Characters/line: 40 80

A character set of 64 ASClI characters, including upper case alphabetics, numerics, and special symbols is displayed in green against a dark background. Each character is formed by a 7-by-9 dot matrix.

Many keyboards are available for the 3277 Display Station, but only the 66-or 78-key EBCDI C typewriter-style keyboard can be used when the 3277 is employed as an operator station attached to the 3791 Controller. The 78-key version of the typewriter-style keyboard includes 12 Program Function keys, which are defined by the application program.

Not all features for the 3277 display stations are supported when attached to a 3791 controller. The following features are supported: Audible Alarm, Operator Identity Card Reader, Keyboard Numeric Lock, and Security Keylock.

See Report C25-491-101 for complete details on the 3270 components, including 3277 display stations and 3284, 3286, and 3288 printers.

PRINTED OUTPUT: Printed copy is produced at a rated speed of up to ISS Ipm with a 48-character print belt, 120 Ipm with a 64 character set, and 80 Ipm with a 96 character set by the #4710 and #4711 line printers for the 3791 or #4712 and

#4713 for the 3792. These printers have 80 or 132 print positions and accommodate 6-part, continuous pin-fed forms up to 8 inches (80 columns) or 14Ys inches (132 columns) in width. Horizontal and vertical spacings are 10 characters per inch and 6 lines per inch, respectively. The #4715 printer available with the 3791 operates at 410 Ipm with a 48 character set, 300 Ipm with a 64 character set, and 230 Ipm with a % cbaracter set. This printer provides 132 positions. Other characteristics are similar to the printers above except that program selection between 6 and 8 lines per inch vertical spacing is included for Configuration Support #9165 and

#9169.

MAGNETIC TAPE INPUT/OUTPUT: The IBM 3411 Magnetic Tape Unit and Control model 1 can provide input and output to a 3791 Control Unit. Additional magnetic tape capacity is provided by attaching 3410 Magnetic Tape units via the 3411. A total orrour magnetic tape units per system are supported.

DA T A LINK ADAPTER: The Data Link Adapter permits attaching the 3276 Control Display Stations plus 3278 Display Stations and 3287 or 3289 printers to a 3791 via non-switched communications lines. Only SDLC communica-tions protocol and the 1920 character screen format are supported. A maximum of five Data Link Adapter features can be attached to a 3791 controller. The maximum number of 3276 Control Display stations permitted on each Data Link Adapter is also five. A maximum of 80 units in any combination are permitted on the five Data Link adapters.

PRICING

All 3790 components, except the 2741 terminal, are available under the terms of IBM's Rental or Lease Al!reement (LRA) or for purchase. LRA includes prime-shift maintenance; a separate contract is available for purchased units.
