Question to example basic 2 port serial write and

[Sarah83]

Hi!

I run this example, choose my ports and it works.

Then, I changend it. I copied everything and paste it into the programm. So I will have everything double.

But the port configurations should be the same. So I wire the port config part with my two write/read parts.

Now it won't work.

I get a timeout. If I change it into a case and start the two seperate, I will get this error, too.

If I cut everything double, it will work...

But I chose different ports. Why I get this error? Sometimes it still write the values from string to write into string to read after this error.

Hello Sarah,

I've seen your example at labviewforum.de. If the 'RS 232 Test 1' button is true, you transmit the data on COM3 (instead of COM5). This looks confusing and might be the problem.

Hmm, the ports not fixed!

You can chose 3 and 5 or 1 and 6... but here my hardware allows only 5 and 6 (also 6 and 5) and/or 3 and 4 (also 4 and 3)
