A quick "fix" is place "Application.DoEvents();"
My problem is with the event.
I have 6 devices that need to access it in one second for data collection.
It should work like this:
Pressed the button that will access the devices automatically every 10 seconds.
Let's call a timer with 10 seconds INTERVAL.
The application sends the command ID01 to the serial port and awaiting a response.
If do not answer or the answer that comes is different from what I hope, that Reeves command.
In the fifth time, warns that not received the response.
So changes to ID01, and repeat the steps above.
If has answer and what is expected.
So changes to ID02 and repeat the above steps.
Thus even ID06.
Expect the cycle of 10 seconds and restarts the cycle.

Ok.
I understand.
I reanalyzed the code and return to continue.

The method with the command to the serial port is below.
But I can not solve this little problem.
In 10 hours of testing.
Not received data 3 times. This is unacceptable for my application.
How to solve?

We had a problem of not receiving data, and receive duplicate data from the serial port with 6 devices RS485/USB, connected to the pc by a converter USB/RS485.
We solve the problem.
I used the code below.

I have the button code above.
And the code below.
I know there are errors in both: logic and code; Why am I suffering from it.
What I need is this:
The method should run automatically at intervals of 10 seconds.
// We have 6 devices: ID01, ID02, ID03, ID04, ID05, ID06
Send the command to CommPort ID01.
Returned?
Yes! These data and stores it in variables to write to. CSV file after ID06 is checked. Next.
No! 1 second interval. Resends the command ID01.
Repeat this cycle 5 times, If it returns! He did not return the fifth time. Error Alert. Stores this error alert in variable. Next.
We repeat the above steps with the ID02, ID03, ID04, ID05, ID06 and save the data in a file CSV, and location of the data ID that did not return a warning and Error Alert.
Clear the variables and restart the cycle in ID01.
I need a error code for any problems occurs in this method too.
