I recently had to connect to some network equipment via the console port using my trusty USB to serial adapter. This is just a quick post outlining the process on MacOS.
Firstly plug in your USB-to-Serial and find its location under the /dev/ directory.
ls -la /dev/ | grep -i usb # output crw-rw-rw- 1 root wheel 18, 3 26 Jun 09:17 /dev/cu.usbserial-FTDCP0VI crw-rw-rw- 1 root wheel 18, 2 26 Jun 09:17 /dev/tty.usbserial-FTDCP0VI
We are looking for the tty device. From the output above you can see that the device is located at /dev/tty.usbserial-FTDCP0VI
The screen command can be used to connect to the USB to serial device. The command structure is screen <device-path> <console-speed>
screen /dev/tty.usbserial-FTDCP0VI 9600 # Now connected to device router1>
Voila! We are connected to our network device via the console port.
To exit the screen session use the keyboard combination CTRL
Press y at the prompt.
Really kill this window [y/n]
