Environment

  • Linux (Serialport is not available on WSL1)
  • Windows

Dependencies

For GNU Linux openssl, pkg-config and libudev headers are required

  • Ubuntu: sudo apt install pkg-config libudev-dev libssl-dev
  • Fedora: sudo dnf install pkgconf-pkg-config systemd-devel openssl-devel
  • Other: Some Linux distros are providing pkgconf.org's pkgconf package instead of freedesktop.org's pkg-config.

Note

  • If sisterm failed to open your COM port, it may be because the user who ran sisterm does not have privileges to access it. To give yourself access privileges, run: sudo chmod 666 /path/to/serialport, running your program as the super-user (root), or making your program set-userid so that it runs as the owner of the device file.
  • If the characters couldn't be sent, try the --instead-crlf option
