SNA-A OS/2 Asynchronous SNA/APPC Utility 12/30/92
Revisions:
Release 1.3: 06/30/92 - Initial release.
12/30/92 - Made available to customers on OS/2 BBS.
Announce Statement:
-------------------
The SNAAOS2 package is prototype code which extends OS/2's
Communications Manager (EE 1.3 or ES 1.0) to include SNA and APPC
over asynchronous connectivity. This code is PROTOTYPE code and
is NOT a part of the Communications Manager product.
Any service issues or questions will be handled through the
APPC forum on the OS/2 BBS.
NOTES:
1. Distribution/service for this package may be stopped
without notice.
2. Communications Manager's service organization MUST NOT BE
called for anything dealing with this prototype.
3. Consult the User's Guide for installation instructions.
Package contents
-----------------
The SNA-A package is named SNAAOS2 and is available in the Tools Section
of the OS/2 BBS Software Library. The SNAAOS2.ZIP file is downloaded
and unpacked using PKUNZIP2. It contains:
README 1ST *Package Overview
SNAAOS2 SCR *User's guide - IBM Script format.
SNAAOS2 LST *User's guide - ASCII list format.
SNAAOS2 PAK *User's guide - Packed LIST3820 format.
SNAAOS2 EXEBIN *The OS/2 device driver providing the SNA-A
function.
NOTE: Consult the User's Guide for installation instructions!
The VM LIST3820 format version of the User's Guide was packed using the
VM COPY statement to preserve record formats and lengths. To restore the
file, first send the file to a VM host with the following OS/2 command:
SEND SNAAOS2.PAK SNAAOS2 PACKED A (RECFM F LRECL 1024
Then, unpack the file on the VM "A" minidisk with the VM command:
COPY SNAAOS2 PACKED A SNAAOS2 LIST3820 A (UNPACK
Description of the prototype
-----------------------------
SNA-A, also referred to as SNA over async or SDLC over async,
is an extension to the SNA architecture allowing SNA traffic to
flow across asynchronous (start/stop) communications lines. The
prototype replaces the existing OS/2 Communications Manager's
SDLC support with SDLC over async support. All forms of SNA
traffic can make use of this data link including LU6.2 (e.g.,
any APPC TPs), LU0-LU3 (e.g., 3270 emulation, host
printing and file transfer), and also SNA gateway.
What is the advantage of SNA over async?
----------------------------------------
SNA over async is being driven by the laptop market. SNA-A enables
the growing base of laptops which already have the required
communications hardware (internal modem or COM port with an
external modem) gain native access to a SNA network. This
allows customers to take their office based SNA applications
"on the road". Any SNA customer with a salesforce has
a requirement for this. The home office environment is another
potential user of SNA-A. People can use home PC's (without having
to invest in an SDLC adapter) to do terminal emulation into their
office machines (3270, 5250, or an OS/2 window via ATELNET).
What platforms support SNA over async?
---------------------------------------
This prototype allows an OS/2 machine (EE 1.3 or ES 1.0) to connect
with NS/DOS, AS/400 or another OS/2 machine configured with the
prototype.
