I know I can use the Terminal built in to ssh to devices, which is fine, but I have to be able to use my usb-serial port.-Thank you in advance, JordanIn this version, we have focused on the Cocoa frontend, but there have been some good core fixes over so long. Notably, the save-related issues resulting in the advice “dont use 0.9.10″ have been resolved.over network, modem or direct serial links from any computer.
![]() Serial Terminal Emulator Driver You NeedThese drivers are often called Virtual COM Port (VCP) drivers. If you create your own UTP cables, you can easily make one yourself.The driver you need depends on the chipset you are communication with. 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).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 Netgear utility for macI 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. I bought these, but in the end, used the drivers created by the manufacturer.You can simply communicate with the port using the cu (call-up) program:Cu -s 9600 -l /dev/cu.usbserial | tee console.logA tool with a better terminal emulation is picocom:If you prefer a terminal application with a GUI, CoolTerm or goSerial are good choices. While this is paid, it does come with support for many devices: PL2303, CP2102, as well as CH340G.
