In FreeBSD, /dev/tty is what ever tty you're presently logged in on, won't even be a serial port at all if you're SSH'd in. You need something like /dev/ttyd0 (FreeBSD) to specify the first serial port. You probably also need to get OpenBSD to take the getty off that serial port. Not sure how far OpenBSD has diverged from FreeBSD, but in FreeBSD you'd edit /etc/ttys and find the line with ttyd0 and change the keyword on to off, save, then "kill -1 1". One thing concerns me is that I've never run a Unix with no console device enabled, even if it was just an unconnected serial port. Another alternative is that there is a second serial port on the 4801. You just need to bring it out to a DB9. Beware there are two different 2x5 to DB9 wirings, beyond the usual DCE/DTE problems, and the nomenclature is horribly inconsistent. I went through all that to hook up my GPS18, getting the wrong cable the first try. I updated the Soekris wiki on this, so check there to avoid my mistakes. ;-) -Jed _______________________________________________ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
