If random characters appear, you probably did not set 115200,8,n,1.

I'm not too familiar with Hyperterm, but this may help:

- Disconnect the serial cable from Ethernut
- Short pin 2 and 3 of the serial cable
- Type characters into the Hypertem window
- Press Enter

All typed characters should be displayed once only.
Pressing enter should place the cursor on the beginning
of the same line (NOT the next line).
