Hello Dan, Here is a note I wrote myself some years ago, when I last tried it. I like slip because it's simple and does the job. I will try to test it this evening. /etc/ifconfig.sl0 ! /sbin/slattach -h -s 115200 /dev/tty00 inet 192.168.3.129 192.168.3.128 up (IP addresses reversed at one end of the cable). -Andy Ball.
