![]() In fact, that is exactly why USB technology was invented. Since RS-232 ports are slow (there is a non error tolerant copper physical layer) 256 is more than time allows anyway.Īny USB hub can increase the number of serial device connections. RS-232 has been around since Christ was a carpenter so 8 bits in the numerator is all you get. Silicon Labs, Prolific and others make similar chipsets that have their own hardware drivers. ![]() ![]() That FTDI chipset has a USB connection and a RS-232 connection and is a virtual serial port. The windows registry then assigns a COM alias to the hardware and stores some information so that each time that exact device is connected it gets the same COM Alias. Update drivers with the largest database available. For example, ftdi232.inf let's Windows know that an FTDI chipset is a rs232 serial port. Get the latest official Prolific USB-to-Serial Comm port (COM/LPT/Serial) drivers for Windows 11, 10, 8.1, 8, 7, Vista, XP PCs. The hardware driver tells the OS that specific hardware should be treated specially. I was wondering if I can buy a usb hub, would it increase the number of available com port? Just wondering whether anyone have tried that or not. Need to interface labview with multiple arduino boards, but I don't have that many usb port available on my computer.
