I haven't ever used SLIP on FreeBSD, but serial port implementations can be extremely picky about the use of RS-232 control signals. If your null modem doesn't at least support DCD you will likely have problems. In that specific case, slattach -l ... might help (that's a lower-case "L"). In fact, for a null modem cable, I'd expect the -l option would be desirable anyway (but as I said, I haven't used SLIP myself, so that's just conjecture). slattach(8) seems to say the default behavior is to abort if there is no reattach script specified (the -r option) unless you specify -l, so it might even fit the symptoms you describe. In other words, try slattach -l -s 115200 /dev/cuad0 and see if that helps. If both systems have Ethernet ports it would be easy (easier, I suspect) to set up a two-node network with a crossover cable, assuming that's a workable solution for you. - Bob
