110487     DV11/3271 Driver for RSX-11M V3.0  Version: July 1981
 
Submitted by: Digital Equipment Corporation
 
Operating System: RSX-11M V3.0  Source Language: MACRO-11  Memory
Required: 24KW (Driver uses 3.8KW)  Hardware Required: DV11-AA,
DV11-BA, Bell System Modem support; 201A,B,C, 208A,B, 209A, IBM 327D,
3275 or equivalent  Keywords: Data Communications, Device Handlers,
IBM
 
Abstract: The DV11 Driver permits the attachment of IBM 3270 (or
equivalent) terminal equipment to PDP-11 computers.
Support is provided for multidropped IBM 3271 or 3275
information display systems on leased or private
synchronous communication facilities. Through the use of
this driver and an appropriately coded application
program, 3271 subsystems see no difference in protocol
or operation from the usual configuration with an IBM
360/370 mainframe and 270X/370X Transmission Control
Unit.
 
The system provides easy to use input-output directives
which perform all basic functions necessary to
communicate with multiple 3270 display systems on
multiple communication lines. It is implemented as a
single RSX-11M executive-resident driver module; there
are no operating system changes required. A system
generation is necessary to install the driver. All 3270
programming is the responsibility of the user, i.e., he
or she must construct appropriate 3270 data streams
including the proper command codes, orders, attribute
characters, and text. The driver will not generate or
modify such data other than for code translation
purposes.
 
Notes: This package supports the 3270 (or equivalent) hardware;
3271 model 1 or 2 on a leased or private full or half
duplex communication line facilities through appropriate
Bell series 200 or equivalent modems, IBM 3275 remote or
stand alone terminal in a polled mode, up to 32 IBM 3277
model 1 or 2, 3284 or 3286 terminals on each control
unit, up to 32 control units may be dropped on each
line. Support is provided for up to four DV11
interfaces, transmission speed of up to 9600 bps per
line, and both EBCDIC or ASCII codes.
The complete user's manual is on the tape only. The
Write-Up (AA) contains required release notes.
 
Restrictions: Driver does not run under RSX-11M on some systems
configured with extended memory unless modified up to
proper rev level of RSX-11M.
