First of all, thank you for your hints and suggestions.
I answer only now because I wanted to take some time to look around a little bit. I saw for example the sys/dev/ic/vga.c driver does support this IOCTL, which would allow me to read a character. Would this approach work only when VGA mode is used (I don't know how this works actually in NetBSD)? And, to support something like VCS-like, where may I start to look? Thank you very much, Enrico thank you very much again Michael and Brian for your kind replies and support. Enrico
