and the response is:
sun has changed the main board and it works again! circuit is damaged.
and i i have the same problem on my Ultra5. It seems that the serial
ports get easily damaged, according to Lefteris Skapetis.
Here is the commands to test your serial port:
halt your machine, and when you get prompt ok:
ok setenv input-device ttya
it works only if you have no sun keyboard attached
to retrieve default parameters, press stop N when you power on.
