You are most probably absolutely right, since all the serial port connection encounters that I had, were instrument based, and they definitely like a line-based approach. As in: SNAP?1,2,4,10,11; 0x0a. They would definitely hang up if the termination character was not there, similar to an incomplete sentence. 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. Serial Debugging using a Raw File 1. Select your haiku image then click settings. Select Serial ports. Tick the tickbox 'Enable Serial port'. Change Port Mode to 'Raw File'. Then set the name and directory of the file to be saved in File Path. And click start (virtual machine) or double click your Haiku image. Virtualbox - 5.0.6 The adapter is identified as a 'Prolific Technology, Inc. PL2303 Serial Port' using /dev/ttyUSB0 On the host, I have verified the cable works through.
This tutorial explains how to enable serial port access in virtualmachines running in a VirtualBox.environment on Mac OS X. The presented approach uses the serial portsavailable on the OS X system and will propagate them to the virtualmachine.
1. Find the Serial Ports¶
The handles for the serial port we will use later on are:
/dev/cu.Repleo-CH341-00302414/dev/cu.Repleo-PL2303-00002314
Note, that in this case two serial adapters are connected on themachine, and the tail of the handle is dependent on the port to whichthe adapter is connected. This tail may change if the USB to Serialcable is connected to a different port.

2. Configure VirtualBox¶
Virtualbox Serial Port Connection Adapters
Start VirtualBox and before firing up a virtual machine, select thesettings menu. Within the settings menu, select the ports tab. Pleasemake sure the virtual machine is really turned off, and not in a savedstate, otherwise you won’t be able to make changes to thisconfiguration. Enable the serial port and select the mode: Hostdevice and fill in the device path.
3. Start the Virtual Machine¶
Start the virtual machine, make sure that the virtual ports are not usedby other applications. The virtual machine will now show you the serialports. For example after a linux boot, run the following command:dmesg|grepserial
In our case we configured both serial ports.
4. Access the Serial Ports¶
In Linux, open for example Minicom on the command line(minicom-con) and configure the port.
Virtualbox Serial Port Tcp
Enter the local device handle, and please make sure hardware handshakeis turned off (except if you have connected all the RTS/CTS lines). Saveand close the configuration window. You will now be able to send andreceiver data via the serial port in your virtual machine running on anOS X host.
5. Notes on Propagating the USB device to the Virtual Machine¶
Virtualbox Serial Port Connection Settings
VirtualBox allows to propagate a USB device to the virtual machine.Within OS X this sometimes causes an error message that the device isbusy. Currently, the only solution to this problem is to toy around withkextunload, kextload and rebooting.
