qLAPB SOFTWARE FOR ARTIC
Quadron's
qLAPB software provides a complete implementation of the
industry-standard, Link Access Protocol-Balanced (LAP-B) protocol
for ARTIC communication cards that reside in PC workstations
and servers. It utilizes a qLAPB task that runs on the ARTIC
card and contains all frame-level procedure code needed to implement
LAP-B. Versions of qLAPB are available for the Windows NT operating
system.
HIGHLIGHTS
OF qLAPB FOR ARTIC CARDS:
 Supports Windows NToperating systems
Offloads LAP-B processing from the PC to an ARTIC
card
Users can fine-tune performance with multiple LAP-B
parameters
Tasks written with standard C compilers run on host
PC
Diagnostic displays show low-level HDLC activity
as well as frame history
Enables access to standard C library functions and
host memory from ARTIC tasks
Compatible with most ARTIC cards
Other Quadron software can run simultaneously on
the same ARTIC card
| Putting ARTIC to work |
The
I/O-intensive processing required by the LAP-B protocol makes
it ideal for offloading from the host PC onto the ARTIC card.
All levels of LAP-B operate as a single ARTIC task, and require
scant PC resources beyond initialization. |
| API |
The
qLAPB task communicates with a user application through a C-language
Application Programming Interface (API) supplied with qLAPB.
The user application usually resides in the host PC but it can
be a task in the ARTIC card itself with additional use of Quadron's
qCF Developer's Toolkit. Multiple high-speed LAP-B links can
run concurrently with other Quadron-developed protocols running
on the same ARTIC card. |
| Watch what's happening |
Runtime
statistics are automatically collected on low-level HDLC activity
as well as the number and type of frames sent or received. A
frame history buffer can be sized to meet your needs. It displays
sent and received frame information, including frame time, size,
address, type, control field values, and the first 8 bytes. |
| Reduce development
costs |
We've
worked hard to make it easy for you to save time and money. Development
is faster because you use industry-standard C compilers and don't
have to deal with low-level ARTIC code. And it saves money because
multiple tasks and protocols can run simultaneously on one ARTIC
card. |
| Combine qLAPB with
other Quadron software |
You
can use qLAPB by itself or you can combine it with Quadron's
qCF, qX25 and qCOM software. This gives you the potential to
individually configure each ARTIC port for a different protocol
and different line speed.
With the addition of multi-tasking qCF,
you can develop other custom, multiple, concurrently-running
tasks on the ARTIC card. These ARTIC tasks use standard C library
functions, including PC disk I/O, expanded memory access, console
output, date, time, floating point math, and string manipulation.
Use our qX25 to support standard
X.25 protocol communication lines. Additionally, we have qCOM, a basic asynchronous support package.
It can be used to access numerous devices that use async lines,
such as scanners, printers, bar-code readers, control monitors,
or modems that connect to remote computers. |
| Technical support |
Starting
with sample programs supplied with the software, many programmers
who are familiar with the LAP-B protocol, C language, and their
operating system can immediately begin to develop ARTIC applications.
If it's needed, free email, telephone or fax technical support
as well as automatic program updates are available during the
qLAPB warranty period. |
| Hands-on workshop |
For
customers who wish to lay the strongest foundation for development,
Quadron offers a hands-on workshop for qLAPB. This one-day workshop
is available either at our facility in Santa Barbara or at a
location of your choice. The workshop is customized to match
your application and give you a comprehensive view of qLAPB and
ARTIC. It essentially provides an accelerated jump on your project. |
| Software requirements |
To
develop and run qLAPB applications, you will need:
Quadron qLAPB Developer's Toolkit
Quadron qLAPB Runtime Support
For
Windows NT, you will also need:
Microsoft C version 6.0 or Visual C++ version 1.52
for the ARTIC
Microsoft Visual C++ for
the host PC
|
| Hardware requirements |
In
addition to a host PC computer, most members of the ARTIC family
of communication cards can be used. Contact Quadron for details. |
| What to order |
There
are two qLAPB components, the Developer's Toolkit and the Runtime
Support, both of which are needed to create a communications
solution. Note that the OS/2 and DOS versions come packaged together.
Order
the following for your operating system:
Part
# 9301 --- qLAPB Developer's Toolkit for Windows NT
Part # 9201 --- qLAPB Runtime Support
for Windows NT

| How to order ARTIC
hardware |
Quadron
also maintains a stock of ARTIC cards and components for sale
and immediate delivery. Our technical sales people will help
you select the combination that best suits your particular application. |
| How to learn more |
Communication
technology has been our only business since Quadron was founded
in 1986. Since then, we've been assisting people with stock and
custom software, training, and the finest ARTIC development tools.
