Re: serial console, no graphic card

[Pierre Dupond]

Hi,

Thanks for this tip. It was very useful.
However with linux as a host and Netbsd 9.0 as a guest the telnet
command is not very pratical since the arrow keys do not work.

This makes the navigation through the menus quite uncomfortable.

I have used kermit with the following kermit command:
     set host localhost 10023 /raw-socket
and in the conditions described above I was able to play
nicely in the installation program of NetBSD.

I hope this could be useful,

Best regards
