Command Processor Shell
Command Processor Shell
The command processor shell provides console input and output with a limited set of commands. This shell is available for both display-enabled devices and headless devices without keyboard and display screen. For display-enabled devices, include the Console Window component (Cmd.exe) so that the command processor shell can handle input and output through a command-prompt window. Headless devices, on the other hand, typically use a serial port for input and output.
Table 3-5 lists registry settings that you must configure on the target device to use a serial port in conjunction with the command processor shell.
