Hi comrades.
I want to write in the COM port of my PC via C# but it sends this error message: Access to port "COM1" is denied.

Can any one help me?

Thanks.

Hi MTLedari,

could you be more accurate with your question, please?

Hi dude.
The problem is clear, I cannot open any serial port. I know, no device is connected to them. I don't know why i receive this exception. It can be for security reasons, if so, what should i do, to access the my com port?

Hello MTLledari
Please more clearly with this question.
I don't know the particulars of your program. So I don't know the mistake of your program.

Hi!

what we need is the code you're using to access the serial port.:) Then we can look it over and see what's not working.
