Ok. First. Thanks for your reply.

ok, What I was trying to say was. It does not answer my usb-serial
connection after some disconnects and reconnects. :>
It always works after a fresh upload.

After power it off and on, 4-5 times strange things happens.
After a while. Some garbage character appear. Then some more
characters. Usually after a power cycle, trying to bring it back to
known state. Then I lose it totally. So my coding session always ends
with uploading amforth again. Which is a pain. My wish was to never
have to upload amforth again. I can replicate this problem. It always
appear when I connect and disconnect with minicom ~4-5 times.
The garbage characters reminds me of the garbage I saw when I first
had the wrong baud rate.

This is working acceptable, but breaks after reconnecting with mincom
(or ZTerm) ~
4-5. Like described.
LFUSE=0x5f HFUSE=0xdf EFUSE=0xf9

I'm trying atmel defaults. I lost my arduino defaults.

(What does "Start up time PWRDN/RESET 64K CK/ 14 CK + 4,1 ms" mean?
This is kind of cryptic to me.)

Are you using usb? I'm starting to think it is the usb-serial driver I
installed initially.
I hope everyone have patience with my knowledge level.(*noob*) =/
