With the serial port redirection feature, end users can redirect locally connected serial (/dev/ttyS) 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.

Published desktops on RDS hosts
The RDS host that hosts published desktops must have Horizon Agent 7.6 or later installed with the Serial Port Redirection setup option selected. This setup option is deselected by default.

For information about which guest operating systems are supported for RDS hosts, see "System Requirements for Serial Port Redirection" in the Configuring Remote Desktop Features in Horizon document.

You do not need to install serial port device drivers in the RDS host.

Virtual desktops
Virtual desktops must have Horizon Agent 7.9 or later installed with the Serial Port Redirection setup option selected. This setup option is deselected by default.

For information about which guest operating systems are supported for virtual desktops, see "System Requirements for Serial Port Redirection" in the Configuring Remote Desktop Features in Horizon document.

You do not need to install serial port device drivers on the virtual desktop.

Horizon Client computer or client access device
The serial port redirection feature is supported on Linux systems that are supported for this release. Any required serial port device drivers must be installed and the serial port must be operable.
Nested sessions
The serial port redirection feature is supported in published applications that are started from Horizon Client inside published desktops (nested sessions). Horizon Client 4.10 or later must be installed in the published desktops.
The serial port redirection feature has the following limitations when used in a nested session.
  • The number of concurrent users is limited.
  • Users must use matched client and agent versions, for example, Horizon Client 2006 and Horizon Agent 2006.
Display protocols
  • VMware Blast
  • PCoIP (requires Horizon Agent 7.9 or later)
