With the serial port redirection feature, end users can redirect locally connected serial (COM) ports, such as built-in RS232 ports or USB to Serial adapters, to their remote desktops. To support serial port redirection, your Horizon deployment must meet certain software and hardware requirements.

Remote desktops

Remote desktops must have View Agent 6.1.1 or later, or Horizon Agent 7.0 or later, installed with the Serial Port Redirection setup option selected. This setup option is deselected by default.

The following operating systems are supported on virtual desktops (single-session virtual machines).

  • 32-bit or 64-bit Windows 7

  • 32-bit or 64-bit Windows 8.x

  • 32-bit or 64-bit Windows 10

  • Windows Server 2008 R2

  • Windows Server 2012 R2

  • Windows Server 2016

This feature is not currently supported for published desktops or published applications on Windows Server RDS hosts.

Serial port device drivers do not need to be installed in the virtual desktop.

Horizon Client computer or client access device

Serial port redirection is supported on Windows 7, Windows 8.x, and Windows 10 client systems. Any required serial port device drivers must be installed and the serial port must be operable. Serial port redirection is available with Horizon Client for Windows 3.4 and later releases.

Display protocols

  • PCoIP

  • VMware Blast (requires Horizon Agent 7.0 or later)

Serial port redirection is not supported in RDP desktop sessions.
