628 Microcontrollers Debugger Manual
Use Escape sequences to handle redirection of the output data stream. Table 28.14
illustrates the different possible redirections and associated escape sequences where
filename
is a sequence of characters terminated by a control character (e.g., CR) and is
a valid filename.
ESC is the ESC character (ASCII code 27 decimal).
Use these commands anywhere in the output stream.
How to Redirect
By default, an output redirection is set to the TestTerm component window.
The debugger uses the Term_Direct function declared in
terminal.h
to redirect an
output. Listing 28.2 gives the source code in
terminal.c
.
Listing 28.2 Term_Direct Source Code
void Term_Direct(int what, char *fileName)
{
if (what < 1 && what > FROM_FILE) return;
Write(ESC); Write('h');
Write(what + '0');
if (what != TO_WINDOW && what != FROM_KEYS) {
PutString(fileName); Write(CR);
}
}
In this case,
what
is one of the following items:
Table 28.14 Redirections and Associated Escape Sequences
Escape Sequence Function
ESC “h” “1” Output to Terminal window only.
ESC “h” “2” filename Output to both Terminal window and file.
ESC “h” “3” filename Output to file only.
ESC “h” “4” Read from keyboard
ESC “h” “5” filename Read input from file
fileName
ESC “h” “6” filename Output to Terminal window and append to file
ESC “h” “7” filename Append to file only
