Subject: RE: [openrisc] Ethernet Core Performance
I had something similarly.
When I wanted to telnet nothing come to the hosting machine and after a
minute it closed the connection.
I discovered that it helps to press CTRL+J or CTRL+h or CTRL+G (I don't
remember which one). After pressing this data was sent to remote
computer and I could login and do everything. It was like pressing the
"send" button after each command.
Regards,
Igor
