Su2 Serial Port Driver Jun 2026
Windows often requires a specific .inf file or vendor-supplied installer executable to map the SU2 device to a Virtual COM Port. Plug the SU2 hardware into your system.
: Handles hardware-level FIFO (First-In, First-Out) transmission buffers to prevent data loss during high-speed transfers. Supported Operating Systems
If given raw driver files ( .inf , .sys ), open the ( Win + X -> Device Manager ).
For optimal performance, especially in high-speed or timing-critical applications, you can adjust the port properties:
