It's impossible looking at these letters, but I did only this:
- I removed AVR chip from IEC-ATA V2 board
- I connected IEC-ATA through Serial Cable and on 2nd port of IEC-ATA I connected diskdrive
- yes, IEC-ATA can't work, but connection COMPUTER - SERIAL - IECATA - DISKDRIVE works!
when I have AVR on the board serial port hangs and I can't access diskdrive...
So, here's offer Q: can be AVR damaged and this is the problem why serial port hangs?
If yes, I can buy new AVR and flash it and will not hangs?
Thanks for every reply.
