Well… for its intended purpose, I would be using the USB serial port (which hasn't worked, yet, either), to have the laptop detached from the dock, and lighter.  A dmesg from the machine, docked, with a standard boot show a parallel port, I believe "lpt2?", and there is a line of isa0 but with no mention of ports at all.  I show the dmesg out, below.  Before I dumped a dmesg from a boot into my normal OS setup (from a drive on the dock), I ran the commands: 

ttys.sh ttys_before.txt; #after which I plugged in the usb to serial cable
ttys.sh ttys_U.txt; dmesg | tail -3 >> ttys_U.txt #after which I docked the laptop
ttys.sh ttys_U_D.txt; dmesg | tail -4 >> ttys_U_D.txt

and I show a reduced dump of the output files, below (there are large sections where a type of /dev/file shows no output from stty at all, so I'll summarized them, and after I plug in the serial cable and dock, I'll just show diff files output, which is really just the tacked on dmesg files, since nothing changes)

So that's what I've been doing to try to find out what is supposed to be working, so far, since, at first, it wouldn't work, then worked fine under Debian, I thought it would be a process of finding which file represented the dock's port, which seems to be wrong, from what you've told me, and the dock port doesn't seem to be on there at all.  I had been hoping it was one of the configured ttys from the stty dumps, and the "constty" is something that wasn't on until my recent upgrade to 6.1.5, so I had hoped it might have something to do with things.  Anyway, thanks for your help, again.
