Depending on the driver in use - there may be a setting in the
hardware settings/device manager in Windoze control panel. My system
allows me to turn on local echo through the driver in the device
manager. Annoying since my program does that function automatically.

It is device dependent. It may be turned off but may not. Some
devices will return the user input as part of the output, for example,
cell phones. If it can be turned off, the manual should tell you. If
not, most likely it won't be mentioned. Of couse, you can always deal
with it in your softw
The serial port transmit and receive buffers are separate. They are
not tied together. If you have nothing connected to the serial port
and you write something to the port, you will not receive anything.
You obviously have a loopback somewhere in your system. I am using
LV7 and I have written a
Question: did you check your serial port setup to make sure that local
echo was turned off? I see this kind of thing in my machine when I
have local echo turned on. It could be turned on in the LabVIEW serial
port setup or in the Windoze setup.

Afaik, the two buffers are separate and I've never seen the problem
you describe. Do you get the same thing when you run one of the
shipping examples? There's one called LabVIEW <-> Serial.vi that you
could try. If you don't get anything in the serial read of the
example, could you post your VI so
Greetings all:
In LV 7.0 I have a serial port Write/Read problem.I am attempting to
communicate with a fairly "dumb" instrument of custom design. In
testing my LV program (with nothing connected to the serial port), I
try to write a string "blah blah blah". No problem, far a
Mads.
What do you mean by type-cast it
to a string?
Thanks,
