Hi Thank You,

yes that was it, my PRINT-rutines always appende <CR><LF> to each string passed, so that the dot was also followed by cariage return, that was wrong, now I´ve corrected it and it works. I do not need anymore jump the jumper :-)
But never the less, will now add an "real" echo function to my firmware.
Thanks again.

Good Evening,

ok sorry, I´m a little bit stupid. Firstly I thought, you mean the chapter 6 of the controller manual, but it deals about Power Monitoring Functions. Then I found the FlashMagic manal and there are quite good information. OK, I´ve learned, thet after sending the /BOOT-command my controller has to do the IAP-calls setting the Boot-Status-Byte to 1 and then has to reset. After reset it will run the ISP-firmware. OK, so far it does.
When I do this with an external terminal-program, I send "/BOOT<CR><LF>". My controller echoes then to me "/BOOT.<CR><LF>", so I dit unterstand that it has to echoe the dot "." after ther command. It does! So then I can do the operations FlashMagic provides: BlankCheck, and of course program new hex-file. So far if I use an externe Terminal Program.
BUT, if I do so with the FlashMagic´s "Start Bootloader"-function, there is still the error "Start BootROM command - "." incorrectly echoed", but my program is echoing the dot! So what does FM exactly expect here?

Good evening,

then I did not found the right part yet in the docu.
Yes my program parses all serial communiaction and when a string "/BOOT" is received the programm jumps to the routine above and sets the Bits BR in the SSTAT-Register and EBRR in AUXR1.
So I must before send simply the String "/BOOT." back?
