After that, the <STRONG>SLEEP</STRONG> program waitsuntil <NOBR>BOOT-51</NOBR> has fully output its sign-on message at 9600 Baudand is ready for a command. To give the <NOBR>MCS-51</NOBR> board some moretime to recover from reset, <NOBR>ASEM-51</NOBR> is now invoked to assemblethe application program.<BR>When finished, the <NOBR>BOOT-51</NOBR> upload command 'U' is ECHOed to COM2,and the Intel-HEX file is also simply copied to the serial port.<BR>Finally the application program is started at address 8000H with the command<NOBR>"ECHO G 8000 >COM2"</NOBR>.<BR>To test an application program <NOBR><EM>MYPROG.A51</EM></NOBR> with the abovebatch job (stored in a file <NOBR><EM>TEST51.BAT</EM></NOBR>), simply type</BIG></P><P><BIG><BLOCKQUOTE><STRONG><CODE>TEST51 MYPROG</CODE></STRONG></BLOCKQUOTE></BIG></P><P><BIG>at the DOS prompt, and see what you get.<BR>Of course this was only a minimized example! In general you will not onlyhave to modify serial port, baudrate, reset port, and start address foryour local requirements, but also to do something for plausibility checkingand error handling.<BR>For this, the more sophisticated batch file <NOBR><EM>BOOT.BAT</EM></NOBR>has been provided.It allows an easy change of all configuration parameters with any ASCIIeditor. For further information see the commentary inside<NOBR><EM>BOOT.BAT</EM></NOBR>.In principle, <NOBR><EM>BOOT.BAT</EM></NOBR> contains only those configurationdata!
