 To install the basic tools required to compile both the Linux emulator and the firmware images, you can use [Homebrew](https://brew.sh/). Most developers will already have it installed, otherwise follow the instructions at the link. Git and the Xcode tools are automatically installed during the Homebrew installation process, while `meson` needs to be installed separately with the following command:

 The physical layer of the rtxlink protocol is a serial communication, which may either be based on a physical link (UART) or a Virtual COM over USB.
 In case a physical link is used, its configuration is 8 data bits, no parity and either EIA hardware flow control, or CLOCAL mode (3-wire null-modem).

 other than the default one is not mandatory, although an rtxlink host must support at least 115200 bit per second. The protocol tolerates buffering and
 fragmentation of the transmitted data.
