So you can hook up another machine with kermit as the console. If you also add options BREAK_TO_DEBUGGER (and recompile sio.c), you can issue a serial line BREAK (^\-b in kermit) instead of Ctrl-Alt-ESC. To temporarily switch to a serial console, enter -h at the boot prompt. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
