We have a few customers using barcode scanners. Most that I know are
wedge devices (i.e. act like a keyboard).
With this device, it truly depends if SRSS sees it as a serial device.
If you plug it into a Sun Ray, do you see it under $UTDEVROOT/dev/term
From a serial standpoint, as long as there are no special drivers on
the windows standpoint (i.e. it's pure R232), it should work when
coupled with com port mapping. More or less the same concept as serial
based signature capture pads that I know some folks are using.
A few caveats. If your app does not set the serial port parameters, you
must hard code the device to the default of utserial which 9600, 8, N, 1.
If using a SR170, use the B port.
You might have to use the net use command on the windows side and you
can't use that command for serial ports that physically exist on the
Terminal Server.
Sun Ray does support a few USB to Serial Adapters. Since most of these
have different chipsets and what not, we only support a few well known
models that don't make changes very often since we have to ensure they
work with utserial. The list is here.

That list is a bit out of date as I know we have (or perhaps will have)
support for the Prolific chipset.
Also note that things can change. Example the Edgeport 2/1 device
switched to a TI chipset which caused problems. That's been fixed, but
just goes to show that changes happen. QUATECH is another example of a
chipset change that we had to issue a patch for.

Hello SunRay-Users,
Since the scanners matter was recently active, I have a question
here too :)
We have seen in the docs that among different devices Sun Rays
can support USB barcode scanners. In short, how far does this
support go? :)
Is it limited to certain devices or their usage, or does it
stream everything to the application level?
I'll try to describe our situation concerning this problem:
We co-develop a custom application which currently works only
under MS Windows, which is sort of an ERP/CRM/docflow app.
It uses barcodes to identify all printed documents, and our
programmers have developed a utility (for Windows) which can
translate signals from the barcode scanner to Windows system
messages. These in turn are captured by the GUI program and
trigger some activity, i.e. open a dialog to edit the electronic
version of the document.
This was developed using an USB CipherLab-1000 scanner, which
under Windows gets a COM port number and the developed utility
accesses this COM port to wait for input from the scanner.
Now, we discussed deploying this whole application in a customer's
new environment which can be filled with Sun Rays instead of
WinPCs as desktop workplaces - if we get the scanners working
in general and through uttsc in particular.
So far this has not become an experimental project (i.e. I don't
yet know whether this scanner does or does not work with a Sun Ray),
but perhaps the list members know if it works and what caveats to
expect and how to work around them?
In particular, does the Sun Ray appliance and SRS support USB-serial
converters (as one seems to be built in this scanner)?
