Any data written to /dev/console is not multiplexed to all console devices, but only the first active device in the list. The reason behind this, is because it adds a real lot of complexity to the console code, especially related to polling and reading on /dev/console. This weekend I'm going to commit a replacement implementation of /dev/console, which also has this restriction. -- Ed Schouten <[EMAIL PROTECTED]> WWW: http://80386.nl/
