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 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).
