serial-adapter is a useful program for interacting with an application running on baremetal. If a baremetal device (such as a Chili2) is running a serial application (such as ot-cli), then it can be controlled by running serial-adapter, with no arguments, on a POSIX or Windows system.

The serial-adapter program, like all Cascoda host programs, uses the ca821x-posix module, so is compatible with both UART and USB connected Chilis.
