Virtual Serial Port Driver PRO enables the connection of multiple physical ports to one virtual port. A switcher function ensures your application is provided with a free serial port while seemingly connected to a single port. Merging COM ports.
First set up a serial port in VirtualBox. In the Details section for the virtualmachine, click Serial Ports, check Enable Serial Port, set Port Mode to HostPipe, check Create Pipe and put e.g. /tmp/freebsd8vm-socket in Port/File Path.
Now start the virtual machine. Use socat to connect the domain socketcreated by VirtualBox to a pty.
It should be possible to now connect to the serial port with screen. If youdisconnect the screen session the pty will be removed, so the above socatcommand will need to be run again.

Enable serial console in Linux
These instructions apply at least to Debian Lenny, but probably will at leastmostly work on other Linux systems as well.
Uncomment/modify this line in /etc/inittab for serial console.
Tell init to re-read inittab
Now we have to tell grub and the kernel (via grub) to use a serial console aswell. Add the following to /boot/grub/menu.lst
Then find the kernel boot options line, which should look like this

and add arguments to use a serial console Uc browser for windows 7.
Now update the Debian automagic kernel sections
I also added noapic to the kernel options to prevent the system fromperiodically freezing at boot

If rebooting the VM is necessary
It is handy to be able to ssh to the VM. When using the default NAT networkconfiguration for VirtualBox, the only way to make network connections from thehost to the guest system is with port forwarding. The following commands willforward port 2222 on the host to 22 on the guest VM. Unfortunately this makesthe host listen on 0.0.0.0, and I have not found a way to make it only listenlocally.

I am running a certain application on Ubuntu (16.04) in VirtualBox, while VirtualBox is running on Windows 10 (host).
In Simulink (running on my host), I have a simulation where at the last stage, I gather some values. I want to output these values over a serial connection at a certain baud rate to the application that is running on VirtualBox (i.e. QGroundControl station).
So first part of my question - VirtualBox:
In VirtualBox, I enabled the serial port and chose a host pipe in port mode, as shown in:
In the picture you can see that COM6 is used, but I used COM1 and COM2 instead. I got the same result for both.
I am not that used to working with VirtualBox, so I don't really know if this means I have now created a connection between my host and guest or if I still need to activate or connect them in any way?
Second part of my question - Simulink:
In Simulink, I want to output my values using a serial send (because I think that is the easiest way? If there is a better way, please tell me), but if I want to select a port, no ports are shown, as you can see in:
What do I need to do/change in VirtualBox/Simulink to get my COM port to show up?
Last part - MATLAB:

Because in Simulink, no COM ports were shown. I wanted to check for available ports in MATLAB, but apparently all my ports are closed:
If I try to open one of my ports by using the fopen()-command, I get this message:
Error using serial/fopen
Open failed: Port: COM1 is not available. No ports are available.
Use INSTRFIND to determine if other instrument objects are connected to the requested device.
Using 'INSTRFIND' shows that all ports are closed.

First of all, VirtualBox won't create a serial port for your host. So you have to create two virtual COM ports on the host using some other software and bridge these two ports virtually. Then use one port to connect to Simulink and other must be setup in such a way that VM COM port uses this port.
For creating a virtual COM port on Windows I will be using
com0com
fromFaking an RS232 Serial Port. You can use any software you like.After installing com0com, open
setuppg.exe
from C:Program Files (x86)com0com
.Now click apply. Now you will have
COM9
and COM10
bridged (it's like COM9
and COM10
are internally connected).Next we need to connect
COM9 port in Host
to COM1 port in Guest OS
for that open Oracle VM VirtualBox Manager
and open the settings of your required virtual machine. Now, select Serial Ports and setup like shown below and click OK.NOTE: Windows provides legacy names only for COM ports 1 through to 9. https://websitetree420.weebly.com/blog/pdf-formats-explained. For all other COM ports you must use the full device naming convention under Windows. So if you decide to use
COM10
instead of COM9
, using COM10
at Path/Address
won't work. Instead you have to use .COM10
.Now start your virtual machine, and your ports are ready. Now ports will be shown in Simulink and connect to
COM10
in this scenario and in the virtual machine, connect your QGroundControl station
to COM1
