I want to connect with my serial Port using PuTTY program, but it's not possible, when I ckick 'open' nothing happens. I only hear a 'Beep, Beep'.. under a Windows 7 on MAC OS X with VirtualBox
Hi, I’m attempting to use putty to get a serial window working. I’ve followed the tutorial in Docs and downloaded the patch etc. When the core is in listening mode (Flashing blue) the core appears in device manager and using the terminal I can get the device ID. To use PuTTY for your serial COM connections, follow these steps: Figure out the COM port you’ll be using. Switch the Connection Type to Serial. Edit the Serial Line to match the COM port you want to use. Edit the Speed to match the BAUD Rate you want to use. Select the Serial.

The first thing I'd do is make sure you can connect to your external device using the Host OS directly. Since you're on a Mac you can use screen from the command line (since you're using 9600 baud):
If that doesn't work then you're dead in the water.
Then make sure your host's serial port is exposed to your Virtual client. From your host Virtualbox settings you'll need to pass through your serial port (like here https://superuser.com/questions/436049/how-to-use-host-serial-port-from-guest-in-virtualbox).
In Putty then you should be able to connect to the COM port you passed through.
Had this problem and found the solution.Putty wont open a connection from the 'Serial' tab in the left column.Choose 'Session' instead and select the checkbox for Serial.

Putty Serial Connection Windows 10
Putty Connect To Serial Portable
Configuration:
- Windows 7
- putty 0.67
- plink 0.67
Problem
I am trying to use plink to open a serial port connection on COM9.
Using PuTTY I can open the serial connection on COM9 and I have a saved session for that serial connection.
The COM PORT settings are:
- Baud: 115200
- Data: 8-bits
- Stop: 1-bit
- Parity: None
- Flow Control: None
When I try and use plink instead of PuTTY, I get the following errors:
But if I use the saved PuTTY session for COM9, it works!
However, I cannot use saved sessions, as my aim is to use plink with Expect to automate testing with the Device connected by serial, and will be on different machines and different COM ports.

I already know the answer, but I googled the problem and saw similar questions with no answers. Hopefully, the next person to Google this will find this and it will save them some trouble.
This problem is Windows OS specific.
Putty Serial Port Commands
On Windows, addressing a COM port greater than COM9 requires special addressing.
From COM1 to COM9 you identify them as just that e.g. COM1, COM2, etc, but over COM9 you have to address them in a special way, for COM10 you must identify it as .COM10, and so on.
So, I tried this and it works:
I don't know why the special COM port addressing format is required for plink, and why it is required for COM9, which shouldn't need it. When using serial to COM1 it works without it. PuTTY doesn't seem to care either.
