41CL Self-Update

[aurelio]

I'm trying now to repeat these operations with the PC which I use daily at work.
Unfortunately it has a not working integrated RS232; I discovered it during a previous attempt (a manual update) few months ago, sure I talked about it on this forum when Sylvain left a tutorial on how to test the serial port...(thanks once more time) .

For this reason I bought a USB/serial adapter
Not without difficulties I found the drivers for windows 7 (with the cdrom were supplyed just the x32 ones), then I tryed to connect the calculator, of course after checking to have properly set the COM25 resulting from the serial adapter, in place of the COM1 default which as said is not working..
What I got was that the calculator stopped in RECEIVING... and there's no way to have a LOST MEMORY (I had to perform a hardware reset, taking apart the board from the calculator)

I have rechecked the connection the setup of the COM25 related to the usb adapter (4800......etc.) seems to be everything OK but three attempts with the same result: anyone have experienced the same problem while using a serial adapter?
