A virtual machine can use up to four virtual serial ports. You can connect the virtual serial port to a physical serial port or to a file on the host computer. You can also use a host-side-named pipe to set up a direct connection between two virtual machines or a connection between a virtual machine and an application on the host computer. In addition, you can use a port or a Virtual Serial Port Concentrator (vSPC) URI to connect a serial port over the network.

Prerequisites

• Familiarize yourself with the different media types that the port can access, vSPC connections, and any conditions that might apply. See vSphere Virtual Machine Administration .
• To connect a serial port over a network, add a Firewall rule set. See vSphere Virtual Machine Administration .
• Required privilege: Virtual Machine . Configuration . Add or Remove Device Power off the virtual machine.

Procedure

1. Click Virtual Machines in the VMware Host Client inventory.
2. Right-click a virtual machine in the list and select Edit settings from the pop-up menu.
3. On the Virtual Hardware tab, select Add other device and select Serial Port .

1. Type a name for the pipe in the Pipe name field
2. Select the Near End and Far End of the pipe from the drop-down menus.

1. From the Direction drop-down menu, select Server or Client .
2. Type the port URI. The URI is the remote end of the serial port to which the serial port of the virtual machine should connect.
3. If vSPC is used as an intermediate step to access all virtual machines through a single IP address, select Use Virtual Serial Port Concentrator and enter the vSPC URI location.

Example: Establishing Serial Port Network Connections to a Client or Server Without Authentication Parameters

If you do not use vSPC and you configure your virtual machine with a serial port connected as a server with a telnet://:12345 URI, you can connect to your virtual machine’s serial port from your Linux or Windows operating system.

telnet yourESXiServerIPAddress 12345

Similarly, if you run the Telnet Server on your Linux system on port 23 ( telnet://yourLinuxBox:23 ), you configure the virtual machine as a client URI.

You can connect the virtual serial port to a physical serial port or to a file on the host computer. You can also use a host-side named pipe to set up a direct connection between two virtual machines or a connection between a virtual machine and an application on the host computer. In addition, you can use a port or vSPC URI to connect a serial port over the network. A virtual machine can use up to 32 serial ports.

Important: With virtual hardware version 11 and later, if you configure a virtual machine without serial ports, they are entirely removed from the virtual chipset and they are not visible to the virtual machine OS.

Prerequisites

• Verify that the virtual machine is powered off.
• Check that you know the correct media types for the port to access, vSPC connections, and any conditions that might apply. See Using Serial Ports with vSphere Virtual Machines.
• To connect a serial port over a network, add a Firewall rule set. See Adding a Firewall Rule Set for Serial Port Network Connections.
• To use authentication parameter with network serial port connections, see Authentication Parameters for Virtual Serial Port Network Connections.
• Required privilege: Virtual Machine . Configuration . Add or Remove Device

Procedure

1. Right-click a virtual machine in the inventory and select Edit Settings .
2. On the Virtual Hardware tab, click the Add New Device button.
3. Select Serial Port from the drop-down menu.

1. Enter a name for the pipe in the Pipe Name field.
2. Select the Near end and Far end of the pipe from the drop-down menus.

1. Select the network backing.
   • To have the virtual machine monitor incoming connections from other hosts, select Server .
   • To have the virtual machine initiate a connection to another host, select Client .
2. Enter a Port URI . The URI is the remote end of the serial port to which the virtual machine’s serial port should connect.
3. If vSPC is used as an intermediate step to access all virtual machines through a single IP address, select Use Virtual Serial Port Concentrator and enter the vSPC URI location.

Select this option only for guest operating systems that use serial ports in polled mode. This option prevents the guest from consuming excessive CPUs.

Example: Establishing Serial Port Network Connections to a Client or Server Without Authentication Parameters

If you do not use vSPC and you configure your virtual machine with a serial port connected as a server with a telnet://:12345 URI, you can connect to your virtual machine’s serial port from your Linux or Windows operating system.

telnet yourESXiServerIPAddress 12345

Similarly, if you run the Telnet Server on your Linux system on port 23 ( telnet://yourLinuxBox:23 ), you configure the virtual machine as a client URI.

With serial port redirection, you can redirect locally connected serial (/dev/ttyS) ports, such as built-in RS232 ports and USB-to-serial adapters. Devices such as printers, bar code readers, and other serial devices can be connected to these ports and used in virtual desktops and RDS-hosted desktops.

If a Horizon administrator has configured the serial port redirection feature, and if you use the VMware Blast or PCoIP display protocol, serial port redirection works in the virtual desktop or RDS-hosted desktop without further configuration. For example, /dev/ttyS0 on the local client system is redirected as COM1 on the remote desktop. Serial port /dev/ttyS1 is redirected as COM2. If the /dev/ttyS port is already in use, it is mapped to avoid conflicts. For example, if COM1 and COM2 exist on the remote desktop, /dev/ttyS0 on the client system is mapped to COM3 by default.

You must have any required device drivers installed on the local client system, but you do not need to install the device drivers on the remote desktop. For example, if you use a USB-to-serial adapter that requires specific device drivers to work on your local client system, you must install those drivers, but only on the client system.

Important: If you are using a device that plugs in to a USB-to-serial adapter, do not connect the device from the Connect USB Device menu in Horizon Client . Doing so routes the device through USB redirection and bypasses the serial port redirection feature.

Tips for Using the Serial Port Redirection Feature

• Click the serial port icon ( ) in the system tray or notification area of the remote desktop to connect, disconnect, or customize the mapped /dev/ttyS ports. When you click the serial port icon, the Serial COM Redirection for VMware Horizon context menu appears. If an administrator has locked the configuration, the items in the context menu are dimmed. The icon appears only if a Horizon administrator has configured the serial port redirection feature and all requirements are met. For more information, see the «System Requirements for Serial Port Redirection» topic in the VMware Horizon Client for Linux Installation and Setup Guide document.
• In the context menu, the port items are listed as port mapped to port , for example, /dev/ttyS0 mapped to COM1 . The first port, which is /dev/ttyS0 in this example, is the physical port or the USB-to-serial adapter on the local client system. The second port, which is COM1 in this example, is the port used in the remote desktop.
• To select the Port Properties command, right-click a /dev/ttyS port. In the COM Properties dialog box, you can configure a port to connect automatically when a remote desktop session is started, or you can ignore DSR (data-set-ready signal), which is required for some modems and other devices. You can also change the port number that the remote desktop uses. For example, if the /dev/ttyS0 port on the client system is mapped to COM3 in the remote desktop, you can change the port number to COM1. If COM1 exists in the remote desktop, you might see COM1 (Overlapped) . You can still use this overlapped port. The remote desktop can receive serial data through the port from the server and also from the client system.
• Connect to a mapped COM port by selecting Connect to use the port in the remote desktop. When a redirected COM port is opened and in use on a remote desktop, you cannot access the port on the local computer. Conversely, when a /dev/ttyS port is in use on the local computer, you cannot access the port on the remote desktop.
• You can then select the Disconnect command to disconnect and make the physical COM port available for use on the client computer.

Viewing Information About Redirected Serial Ports

For remote desktops that have Horizon Agent 2106 or later installed, you can view details about redirected serial ports by running the vmwsprrdctl.exe console utility on the desktop. The utility is supported on both remote desktop sessions and nested mode sessions.

The utility is located on the remote desktop in C:\Program Files\Common Files\VMware\SerialPortRedirection\Agent\vmwsprrdctl.exe .

To get help with command-line usage for the utility:

1. Start a remote desktop session and open a console window on the desktop.
2. Change to the directory location of the utility and run the following command.

The utility provides the following information.

• Hardware ID information:
  • USB device VID (Vendor ID)
  • USB device PID (Product ID)
  • USB device Rev (Product Revision)

  Note: The utility does not provide the source COM port number on the client or the COM port redirection status for any virtual COM port on the agent redirected from a client port that uses a USB-to-serial adapter.

  You can add up to four serial (COM) ports to a virtual machine. Virtual serial ports can output to physical serial ports, files, or named pipes.

  You might want to add a virtual serial port to a virtual machine to make devices such as modems and printers available to the virtual machine. You can also use virtual ports to send debugging data from a virtual machine to the host system or to another virtual machine.

  Note: The virtual printer feature configures a serial port to make host printers available to the guest. You do not need to install additional drivers in the virtual machine.

  Prerequisites

  Power off the virtual machine.

  Procedure

  1. Select the virtual machine and select VM > Settings .
  2. On the Hardware tab, click Add .
  3. In the Add Hardware wizard, select Serial Port .
  4. Click Finish to add the virtual serial port to the virtual machine.
  5. Select where the virtual serial port sends output.
     

     Option	Description
     Use a physical parallel port	Send output to a physical serial port on the host system.
     Use output file	Send output to a file on the host system. Either locate an existing output file or browse to a directory and type a filename to create a new output file.
     Output to named pipe	Set up a direct connection between two virtual machines, or a connection between a virtual machine and an application on the host system.

  6. If you selected Output to named pipe , configure the named pipe.
     1. (Windows host) Use the default pipe name, or type another pipe name.

     This option is useful if you are using debugging tools that communicate over a serial connection. If the serial port in the guest operating system is being used in polled mode rather than interrupt mode, you might notice performance issues. This option forces the virtual machine to yield processor time if the only task it is trying to do is poll the virtual serial port.

     What to do next

     If you set up a connection between two virtual machines, the first virtual machine is set up as the server. Repeat this procedure for the second virtual machine, but set it up as the client by selecting This end is the client when you configure the named pipe.
