Software Product Description
PRODUCT NAME:

RSX-110/3271 Protocol Emulator (PE), Version 1

DESCRIPTION:
The RSX-11D/3271 Protocol Emulator (PE) permits
applications tasks running under RSX-11D to communicate interactively with tasks in an IBM 360 or 370
system. It is a tool to aid in implementing complex
applications requiring on-line information entry and
retrieval, file transfer and inter-task communications
capabilities between IBM 360 or 370 and PDP-11
RSX-11D systems. The user task in RSX-11 0 presents
itself to the IBM system as an IBM 3277 display unit
attached to an IBM 3271 control unit operating in
slave mode.
The emulator operates as a device driver under RSX110, maintaining the synchronous line discipline on
one side and interfacing with the user tasks on the
other. The PE module supports up to six synchronous
lines, each of which can be viewed by the 360 or 370
as a 3271 controller. Each pseudo controller supports, at most, 32 RSX-11 0 user tasks. The maximum
number of supported lines and user tasks is a function of application requirements and buffer constraints.

Line Discipline - The communications discipline
used by the 3271 PE is the 3271 subset of IBM's BSC
(Binary Synchronous Communications) protocol using
EBCDIC code. Specifically, this subset of BSC supports operation of full or half-duplex leased lines in
either pOint-to-point or multipoint configurations at
transmission speeds up to 9600 bits per second. The
protocol does not support switched facilities using
contention line control.
The PE does not provide transparent BSC capability,
but it can share a multidrop line with terminals functioning in transparent or non-transparent mode.

User Task Interface - Applications tasks access the
emulator via 010 MACRO calls.
The emulator does not interpret or insert 3270 orders
for formatted screen emulation; therefore, the applications task is responsible for formatting and interpreting the data portion of the messages being sent
to and received from the 360 or 370 system
MINIMUM HARDWARE REQUIRED:
A minimum RSX-11D configuration with:
• an additional 8K words of memory
• a synchronous interface: either a DV11, a DUP11
with KG11, or a DU11 with KG11

• Bell 201 or 208 modems or equivalent. Operation
with other modems is not precluded, but warranted
support does not apply in these cases.
• A master host 360/370 configuration which must include a 2701 Data Adapter, a 2703 Transmission
Control Unit, a 3704 or 3705 Transmission
Controller, or a System/370 Model 135 Integrated
Communications Adapter.
OPTIONAL HARDWARE:
• 1K words additional memory for each additional
synchronous line after one.
PREREQUISITE SOFTWARE:
RSX-11D operating system, Version 6.1 or 6.2.
A master/host system running one of the following
operating systems and applications task interfaces:
• OS, CICS/OS Standard Version 2
• OS/VS 1 or OS/VS2 or DOS/VS, CICS/VS
Operation with other operating systems and task interfaces is not precluded, but warranted support does
not apply in those cases.
OPTIONAL SOFTWARE:
None
SUPPORT CATEGORY:
A - Software Support will be provided as listed in
the Software Support Categories Addendum to this
SPD.
UPDATE POLICY:
Software Updates, if any, released by DIGITAL during
the one (1) year period following installation, will be
provided to the customer for a media charge. After
the first year, updates, if any, will be made according
to then prevailing DIGITAL policies.
ORDERING INFORMATION:
This software is furnished under a license for use on
a single CPU and can be copied and modified (with
inclusion of DIGITAL's copyright notice) only for use
on such CPU, except as may otherwise be provided
in writing by DIGITAL.
Options with no support services are only available
after the purchase of one full-support license. When a
software license is ordered without support services,
the category of support applicable to such software is
Category C.

CUSTOMER RESPONSIBILITIES
BEFORE installation of the SOFTWARE, the customer
must:
1. Obtain, install, and demonstrate operational to
DIGITAL's satisfaction any modems and other
equipment and facilities necessary to interface
to DIGITAL's communications line interfaces and
terminals.
2. Install or have installed all hardware, including
terminals, to be used on the system.
3. Generate any and all IBM systems that will be
communicating with the 3271 PE to DIGITAL's
satisfaction.
4. Make available to DIGITAL personnel all hardware, including communications facilities and
terminals, to be used during installation and acceptance testing for a reasonable period of time
each day, as mutually agreed upon by DIGITAL
and customer, until acceptance criteria are satisfied.
S. Provide access privileges and machine time on
any and all IBM systems on which the installation is to be performed.

6. Provide an IBM application program that performs a write followed by a read to the 3271 PE.
7. Edit the PDP-11 test program to include the
correct message to be sent to the IBM system
(or supply DIGITAL personnel with this message).
Delays caused by any failure to meet these responsibilities will be charged at the then prevailing rate for
time and materials.
