Setting up a Serial Terminal with Mac. OS X. You have now established a serial communication with your board. You can interact with your board by entering common Linux commands. For a summary of useful commands, see Common commands for the Intel® Edison board. Connecting to the serial console on Mac and Linux uses essentially the same process. Neither operating system needs drivers installed. On MacOSX, Terminal comes installed. On Linux, there are a variety such as gnome-terminal (called Terminal) or Konsole on KDE. The port is like a door through which your board can communicate with your computer using USB. We're going to use Terminal to determine what port the board is using. The easiest way to determine which port the board is using is to first check without the board plugged in. On Mac, open Terminal and type the following: ls /dev/tty.

I try to establish a serial connection with my MacBook (High Sierra 10.13.1) and need help.
I have a Belkin F5U103V USB-to-serial adapter and want to connect to a HP ProCurve switch. I tried to follow several instructions such as this one or the installation instructions in the ZIP-archive of this driver but none of this worked.
After the installation of the mentioned driver of my device, all of the instructions I found asked me to use the
ls /dev/tty.*
, ls /dev/*usb*
or the ls /dev/cu.*
command to find out the device which is associated with the usb port. This is the step wich fails for me.The
ls /dev/*usb*
command does not return a result at all. The two other commands return/dev/cu.Bluetooth-Incoming-Port Iso 9001 2015 checklist pdf.
/dev/cu.SOC
/dev/cu.MALS
/dev/cu.iPhonevonFirstnameLastname-Wire
(and the same name with
tty.
instead of cu.
respectively), which means, that I am not able to find a serial device which is associated with the usb port.After the installation of the driver I had a 'USB serial controller' in my network settings. When I change the modem to a 'Null modem', set the baud to 9600 and try to connect, a popup appears that says that my device is not available.
Strangely, when I try to connect to the switch via Serial App, I can see the USB serial port and it works perfectly to connect to the switch which means that the USB-to-serial device works fine generally.
I want to open the serial port with the build in
screen
command preferably (screen <device> <baud>
). What is the reason why I cannot find the device as mentioned in the instructions and how can I use the build-in tools to open a serial connection without 3rd party software?If it is relevant, I have a MacBook Pro 2016 which means that I have USB-to-serial adapter which is plugged in into a USB-c-to-USB adapter.

You need a specific driver for the USB-Serial device. MacOS support for these - especially in recent versions of the OS - is spotty, at best. You need to check even ones that claim MacOS support because their support might have worked up until about 10.6, when Apple started getting serious about kernel and driver security, sandboxing, etc.

FWIW, USB-Serial devices based on the Prolific chipset seem to have most luck.
Serial.app works because it uses its own driver, not the /dev device. For most uses, I'd say this app is required if you want to maintain sanity.

A late entry to this question, but hopefully this will help someone:
For serial comms using a late-model Mac, my experience is that there are two things you should know:
These are not intended as 'commercial endorsements'; I have absolutely no financial stake in either. They're simply tools that allowed me to get where I needed to be, and ended hours of failure and frustration. Everything else I tried was half-baked and not-ready-for-prime-time: Unsigned drivers, drivers that occasionally worked, drivers provided on mini-CD hard media (?! - didn't even know they made these any longer until I bought the Tripp-Lite cable), interface cables that 'just didn't work', etc, etc, etc. If you're interested, there are a few more details posted on my GitHub page.
And as far as CoolTerm goes: I used this program for years, and really liked it. Unfortunately, running it now (HighSierra 10.13.6) generates 'warnings' that it's not optimized for Mac. I don't know if there's a 64-bit version coming or not.
Hope that helps.

I've been using CoolTerm since 2014 to serial talk with the barometer chip hooked up to my Arduino. Straight USB, no USB to serial cord needed.Pretty easy to set up, and plays nice with AppleScript.Free, so you've little to lose trying it.

Version 1.6.0.3.708:New/Changed Features:
- Added 'Open Recent' menu item. Recent items are saved between sessions.
- Added 'Close All' menu to close all open window.
- Added capability to restore the previous sessions. If enabled via the Preferences, the current session is saved if CoolTerm is quit via File/Quit (macOS/Linux) or File/Exit (Windows). CoolTerm will attempt to restore all the open terminal windows from the previous session at the next start.
- Added context menu for Copy/Paste operations to plain text display.
- Replaced option to stop Autoscrolling with option to pause the display instead. When enabled, the display contents are not updated until pausing the display is disabled again. Opening and closing the port automatically un-pauses the display.
- Added baud rate selector in the connections to allow setting a custom baudrate. The custom baudrate can be saved as part of the connection settings.
- The font size for text input fields (line mode input field 'Send String' input field) can now be set independently via the preferences.
- Added preferences option to automatically refresh the list of serial ports when opening the connection options.
- Added preferences option to check for development releases when checking for updates.
- [Mac] Added the following AppleScript commands:
- WindowIDfromName(WindowName as string) as integer
- SaveSetting(ID as integer, FilePath as String) as boolean
- CoolTermVersion as string
- RescanSerialPorts
- SerialPortCount as integer
- SerialPortName(SerialPortIndex as integer) as string
- GetCurrentSerialPort(ID as integer) as integer
- SetCurrentSerialPort(ID as integer, SerialPortIndex as integer) as boolean
- GetParameter(ID as integer, ParameterName as string) as string
- SetParameter(ID as integer, ParameterName as string, Value as string) as boolean
- GetAllParameters(ID as integer) as string
- Added support for dark mode on platforms that support it (such as macOS Mojave).
- Supporting Raspberry Pi
- Default is now 64-bit for all platforms (except Raspberry Pi)
Mac Terminal Open Serial Port
Improvements:
- File/Save menu item is now permanently enabled. Selecting File/Save when settings have not previously been saved will present the user with a 'Save As..' dialog.
- Connection Settings saved as default no longer contain the selected serial port and window position. New windows using the default settings will select the first available port rather than trying to force a port that may or may not be available.
- The text and background color settings for the text display are now also applied ot the line mode input text field.
Bug Fixes and Stability Improvements:
Mac Terminal Com Port
- Fixed bug where the receive buffer size wouldn't be set upon loading of connection settings.
- Fixed bug that causes setting to not be properly loaded on Mac when starting CoolTerm for the command line with a settings file as argument or when starting CoolTerm by double-clicking a settings file or dragging it onto the CoolTerm icon.
- [Mac] Disabled splash window for macOS Sierra and newer.
