UBUNTU SOCAT TUTORIAL SERIAL

The result is that any data sent through the terminal will be echoed back to it.Ĭonnect a serial device to the port and verify its operation using commands or an application that supports the equipment. Doing this will short the serial port’s Rx and Tx pins. Short Pin 2 and 3 of the physical serial port.

We can perform the verification using two different methods.

I have selected Cutecom to fill this role. We need to use a serial port terminal on the guest operating system to verify our configuration. The Kubuntu virtual machine will map COM1, or the serial port with an I/O port of 0x3f8 and IRQ of 4 to /dev/ttyS0. Now it’s time to verify that the configuration works as intended. The screenshot below displays the Virtual Box Configuration.Īll you need to do is to set these three fields to your designated values and you are finished. As previously mentioned, we will be connecting to COM3 so use that value here.

Port Path: The “Host Device” port mode field uses the physical device port number on the physical host.

Port Mode: This parameter needs to be set to “Host Device” so we can connect a virtual port to a physical one.

Remember, this does not refer to the machine’s physical ports. We want to map it to /dev/ttyS0, so COM1 should be selected.

Port Number: This field refers to the port number of the guest operating system.

This needs to be done before any other settings can be changed.

On the Porto Tab select the Enable Serial Port checkbox.

We will be ignoring the IRQ, IO PORT, and Create Pipe fields. When you first open the serial port configuration dialog box on the virtual machine, you will be presented with the Porto tab. This is easy to do if you are aware of what to ignore when in VirtualBox’s serial port configuration dialog. Now we have to configure VirtualBox to connect serial port of the guest operating system to the host’s physical COM port. I chose to use COM3 to avoid confusion, but any port can be accessed by using this method.

The project requires that I attain access to COM3 from the Kubuntu guest installed under a VirtualBox virtual machine.

My computer has four serial ports which Windows defines as COM1, COM2, COM3, and COM4. Interrupt Request (IRQ) | COM 4 | /dev/ttyS3 | 2E8 | 3 Name Under Linux | COM 2 | /dev/ttyS1 | 2F8 | 3

Name Under Windows | COM 1 | /dev/ttyS0 | 3F8| 4 COM2 will equate to /dev/ttyS1 and the pattern will be maintained for all of the serial ports I use. To avoid confusion over which port I am talking about, I will use COM1 on Windows and /dev/ttyS0 on Linux to map these names to the same IO ports and IRQs. The example I will be discussing involves both operating systems. Linux uses a format of /dev/ttyS0, /dev/ttyS1, and so on. On a Windows machine, the ports are named COM1, COM2, etcetera. Windows and Linux use very different naming conventions to identify serial ports. That’s the reason for this post, but before proceeding, let’s talk a little about serial ports. You can use serial port VirtualBox guide , but it also can be tricky. The only drawback is that there are multiple ways to accomplish this, which can be confusing. VirtualBox is an easy-to-configure solution that enables the guest to access the serial port. To perform debugging, access to the host’s serial port is required. To get around this issue, I installed Kubuntu as a guest OS on my Windows host machine. All the extra cables result in a tangled mess and I really like to leave the space open for other equipment like oscilloscopes that I need to complete my work. This can be a problem as there are two reasons why I dislike having multiple computers running at the same time in my workspace. My main operating system is Windows XP, but many projects I am involved in require me to use Linux. This is true no matter what operating system I am using and whether it is on a physical or virtual platform.

Serial port access is critically important in my role as an embedded software engineer.
