Note: In addition to a toolchain and autoconf tools, this requires autotools-archive to be installed.
To build this project, run the following shell commands:
./bootstrap.sh
./configure ${CONFIGURE_FLAGS}
make
To fully clean the repository, run:
./bootstrap.sh clean
Running the server requires a serial port (e.g. /dev/ttyS0):
touch obmc-console.conf ./obmc-console-server --config obmc-console.conf ttyS0
To connect to the server, simply run the client:
./obmc-console-client
To disconnect the client, use the standard ~. combination.
This shows how the host UART connection is abstracted within the BMC as a Unix domain socket.

This supports multiple independent consoles. The socket-id is a unique portion for the unix domain socket created by the obmc-console-server instance. The server needs to know this because it needs to know what to name the pipe; the client needs to know it as it needs to form the abstract socket name to which to connect.
