|
|
* The Contiki shell provides both interactive and batch processing
|
|
* for Contiki.
|
|
*
|
|
* The shell consists of two parts: the shell application and a shell
|
|
* back-end. The shell application contains all the logic of the
|
|
* shell, whereas the shell back-end provides I/O for the
|
|
* shell. Examples of shell back-ends are a serial I/O shell back-end,
|
|
* that allows the shell to operate over a serial connection, and a
|
|
* telnet server back-end, that allows the shell to operate over a
|
|
* TCP/IP telnet connection.
