Thanks Oliver, this looks interesting but I will have to find out to
what range of prices we are looking at

Dear Youri,
well, at least concerning the "good old serial port" I could give you
and everybody a good report since even if no serial ports are available
any more on the Mac itself we address in a certain project over 260
serial devices from a mac. We use Moxa Terminal Servers for that, which
relay serial data to ethernet and thus could be addressed as if they
were a TCP/IP socket. This even works if you have your serial device
spread over a hole campus area - and they are reliable and built for
industrial use. They're not quite cheap, but they work.
This might be an option if you want to address devices with an "old"
serial port - using something like the moxa terminal server you can
forget about all the consumer type serial-to-usb converters which bring
additional failure risks as you wrote. They work for years and since
they use industrial standart ethernet to talk to a mac or pc you're
ready for the future.
Kind regards,
Oliver

Hi,
We have a recurring project (but no time) for developping a solution
with a data acquisition Card from NI.
Unfortunately, these devices are USB and therefore dependent on the
manufacturer's Driver. As Win machines represent 95% of the market not
many manufacturer are willing to develop for Mac machines...
I regret the time when we had good old serial devices (and ports)
without Drivers problem.
An ophtalomologist asked me to develop a little soft to be able to
load datas from his instruments directly in his Mac, but I am very
reluctant as again the only solution would be to use a Keyspan device
which doesn't always work properly.
Same apply for Suunto diving computer, Legos (don't know about the
last version thought)... Very frustrating.
My question is : Is it that difficult to make a kind of
"generic-configurable" driver for USB devices, which used to work with
simple Serial Ports not that long ago?
Cheers,
Youri

Not exactly science perhaps but the latest edition of Lego's robotic
training kit Mindstorms seems to use a visual edition of Labview. The
good news is that it now runs on both Macs and Windows and it is
controlled via a USB device. It can however be a bit tedious to work
with, so my question is has anyone tried to do something in RB?
