I have to say that I don't necessarily agree with the statement. I have had it working on EXACTLY the same system(s) w/ the same cable before, but to satisfy my curiosity and that of those out there ... I just tried a db9 to db9 null-modem cable to no avail ...
I just went so far as to setup a Cisco router w/ reverse telnet so I could monitor what was comming off from the pfSense serial port (set for COM1 in the BIOS .. BTW, as has always been), and see no bits at all comming from the serial device (pfSense). I am very familiar w/ DTE/DCE communications ... worked many years w/ ISPs and modem banks and mainframe comms ... not my first exposure to or w/ DTE/DCE comms or null-modem communications. My concern is that it worked before w/ a flat roll over (Cisco) cable ... and you are in fact correct Bill, MOST serial comms between active devices require 2/3x .... but since trying to set this up in 0.84,5,6.x and having had to use a roll-over cable to get it to work (I did try a null-modem way back when I first set this system up, but couldn't get it to work w/ that connection scema). My suspect is that there has been some handy work on the serial setup in FreeBSD at the OS level .... don't know that for sure .. not real litterate w/ BSDs .. I know a fair bit from the *NIX (Solaris, Linux, AIX) world, but certainly not as up to speed in the FreeBSD realm. I've been pouring over the FreeBSD site for KBs on different serial port configs and there seems to be a fair bit of config you can do to a serial interface as is there in the NIX realm. I don't know what else to say .... but I keep looking and contribute where I can.
