I wrote on years ago by reading /dev/mem. I've just had a look for the source, but no longer seem to have it. It is very simple though, just seek to the start of screen memory (ask on one of the PC programmers newsgroups), and read 80x25 bytes (actually, I think it is 80x25 pairs of bytes, otherwise you could use dd to get the screen). Don't forget to make your program suid. Gary -- pub 1024/C001D00D 1996/01/22 Gary Howland <gary@systemics.com> Key fingerprint = 0C FB 60 61 4D 3B 24 7D 1C 89 1D BE 1F EE 09 06
