Unable to upload example 'Blink'

Development Tools Uploading
1

I tried to upload the example 'Blink' to my Arduino Uno R3 and the following error message came:

Sketch uses 924 bytes (2%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't set com-state for "\.\COM3"
Failed uploading: uploading error: exit status 1

I followed the link from the Arduino website:
https://www.arduino.cc/en/Tutorial/BuiltInExamples/Blink
And copied it into my IDE (Arduino IDE 2.3.4) and it returned with this error.
So, I'm not sure what to do... :frowning:

Why did you post in the PLC IDE section of the forum? Your topic has been moved to a more suitable location on the forum.

See if Port monitor error: command 'open' failed: Invalid serial port. Could not connect to COM serial port - #49 by ptillisch helps you.
