Bottom right: male-to-female DB-9 adapter. Bottom center: a USB-to-serial adapter with male DB-9 connector. On the left: regular USB cable with micro-B and mini-B connector. The cables I use for a console.Like mine, the actual conversion from USB to serial is done by a Prolific PL-2303 USB to Serial Bridge Controller buried in the connector. I bought a Icidu C-707607 USB to Serial cable. In addition to a full-featured terminal emulator, Serial includes built-in, user-space drivers for many popular devices, saving you the hassle of finding, installing, and updating drivers.In case the serial port is a DB-9 connector or RJ45 connector, you need a USB-to-serial adapter. Javascript Interface.Serial makes it easy to connect your Mac to almost anything with a serial port, including routers, switches, PBXs, embedded devices and more. Click the right mouse button (or control-click if you have a Mac) and select Edit.
Serial Port Emulator Activation Key Is RequiredYou can also buy a female-to-female DB9 connector, but make sure that the internal wiring is cross-over like is the case with a null modem. The USB-to-serial cable, as well as the network device will have a DB9-male connector. A null modem cable is a cable with DB9-female connectors on both ends. FOR DEVELOPERS: You can use FREE VSPE API key located in the distribution package to get access to internal VSPE functions for your applications.Make sure to also purchase a null modem cable, or a female-to-female DB9 connector. No registration or activation key is required. 1-adb shell command says device/emulator not found-need to reboot to system to use.Virtual Serial Ports Emulator tool (and VSPE API) is free on 32 bit platform and can be used with no charge for any purpose. As with the null modem cable, beware that you might need a cross-over UTP cable. There are cables or adapters that plug into a regular UTP cable. If it is about 1 centimeter long, the cabling is "straight" and it will not work as a serial cable (these straight connectors are used to extend old VGA cables).A way to emulate a serial device (RS232) on Mac that worked for me was by plugging an Arduino (it requires hardware yes, but can emulate many other devices).In case your serial port is a RJ45 connector (which may be the case on network hardware), you also need a DB-9 to RJ-45 convertor. Since this driver is preinstalled on macOS Maverick and higher, it may just work out of the box. The Prolific driver version 1.4.0 created a new device socket under Mac OS X, /dev/cu.usbserial.For most development boards (such as the Arduino or Pycom), you most likely need the USB FTDI driver. Nanjin QinHeng Electronics CH341 (CH340G).For a USB-to-serial adapter with Prolific PL-2303 controller, you can download the driver from the Prolific website or from the manufacturer you bought the cable from. Silicon Laboratories CP210x (CP2102), or You will likely encounter on of these: These drivers are often called Virtual COM Port (VCP) drivers. Mac emulator fbbEven that did not work out of the box, I had to disable the MacOS native driver, enable the FTDI driver and reboot before it worked.Sudo kextunload -b com.apple.driver.AppleUSBFTDISudo kextload -b com.FTDI.driver.FTDIUSBSerialDriverIf that also fails, you can also buy a third party driver from. I resolved this by installing the VCP driver from FTDI Chip. At the time of this writing (spring 2020) no System Extension drivers are available yet, but the Kernel Extensions continue to work (albeit with a warning to the user).The build-in FTDI driver on Mac OS High Sierra had some issues: no device was detected. Especially cheaper USB cables can only be used for powering a device, while the data wires are simply not connected.Since mac OS High Sierra (10.13 and up), you need to allow the driver in the System Preferences Privacy tab, immediately after installation.Since mac OS 10.15, Kernel Extensions are replaced with System Extensions. For these, you need the CP210x USB to UART Bridge VCP driver.First check if your USB cable is correct. /dev/cu.usbserial or /dev/cu.usbserial-DQ008BU0).Some other development boards come with a CP2102 serial controller, including NodeMCU and a Doodle Bot I bought.
