Connecting to Telnet through a macOS program

I am currently trying to code an application for a macOS to control an Arduino. To do this I need to be able to access telnet and send string commands to it. Any ideas on how to do so?

Solution

  • telnet is insecure, inflexible and out of fashion - folks use ssh now. There is no longer even a telnet client in High Sierra.

    Create an empty file called ssh in the partition of your SD card called boot to get in the first time. Then ssh in with:

    ssh pi@<RASPI-IP-ADDRESS>

    and password raspberry.

    Then use:

    sudo raspi-config

    to enable ssh for future boots.
