This command is only for use with semihosted applications when using the debugger interactively in the command-line console.
This command is not required if you launch the debugger within Eclipse or if you use a telnet session to interact directly with the application.
Specifies semihosting input requested by application code. This must be terminated by
\nto tell the debugger that the input is complete.
You can use this command before the input is required by the application code. All input is buffered by the debugger until requested and then discarded when the semihosting operation finishes.
