I really haven't done any usb stuff yet except configure the port. I
have done some testing
with an internal modem using the serial port. The only thing I have
done with usb is list
the devices. It is possible the only way to access most usb devices
is to write a driver for
Rev to access the port.

You could probably do it with X10 devices. I used to control X10
devices with OS 8.6. They
were controlled from the serial port but the new device is USB. I
am writing a stack that will
control the serial and USB ports but haven't been working on it
for a few months. I was able
to configure the ports and do some serial port stuff with the
modem but haven't done much
with the usb port yet. The older X10 took commands in a binary
format if I remember and I
haven't done enough to see how the new X10 devices are controlled
but they've changed
the format. I have written some code for Revolution to convert
between binary, ascii, hex &
numeric that I posted in the Scripters Scrapbook online section.
I did find a program that is
for the Mac that controls X10 devices so I know it can be done but
it may need a driver to
be written so you can do it with Revolution. Until I figure out
what type of info needs to be
sent to the USB device I won't be able to test it without a driver
to be sure if it needs one to
be written or not. If you can figure out how to control an
external serial device from Rev the
old device could be used instead of the new USB one.

Dear friends, I had this crazy idea:
I would like to create a Rev application to control the
temperature of my room. So, I need my application to import the
temperature from a thermometer and switch on/off the heater.
I found documentation for an affordable external device in
internet : http://www.audon.co.uk/io8g.html
It says "Compatible with Profilab DAQ Software. " and "Can
Utilize a Simple Terminal Emulator to Control All Functions"
It says also: "Virtual COM port (VCP) drivers cause the USB
device to appear as an additional COM port available to the PC.
Application software can access the USB device in the same way as
it would access a standard COM port. "
Now, I have some questions:
Can we access the USB device using a standard COM ports from
Revolution?
Can we have Revolution to behave as a terminal Emulator to
control all Functions?
To summarize, do you think I can menage to control this external
device from Revolution?
Thanks a lot.
