These drivers allow you to force the virtual COM port of the USB device so that it does not change even if connected to different USB sockets. Some USB virtual COM-port devices use vendor-specific drivers in place of the Windows-provided drivers (usbser.sys). Get a RS-485-to-RS232 converter to use it as a COM port)Īpplications suited for serial ports often involve sensors, controllers, old check readers, pads, etc. (When connected through RS-485 port Applications might not work at all. Two common protocols for virtual COM are CDC ACM or MCT. The OS can abstract COM ports and treat them like fileshares. Some USB devices function as virtual COM ports, which applications can access in the same way as physical serial port. While most PCs no longer have built-in serial (COM) ports, the ports are easy to add via USB converters.īeware that even if a device can attach to the endpoint via USB directly does not mean it can be redirected via Generic USB Redirection.

These mappings can be used like any other network mappings.įor each COM port, a driver in the OS assigns a symbolic link name such as COM1, COM2, etc, which is then utilized by the applications to access the port. For more information, see Port redirection policies in Citrix Documentation.Ĭlient COM port mapping allows devices attached to the COM ports on the user's endpoint to be used during virtual sessions. In versions 7.0 through 7.8, these settings were only configurable using the registry. LPT and COM port settings are configurable via Studio in XenApp / XenDesktop 7.9 or newer.
