ah... well that could be.  I was a bit concerned when I realized that 
Windows called it COM3

mgetty seems to have editied /etc/ttys like this:

ttyd0  "/usr/local/sbin/mgetty -s 115200" dialup on secure
ttyd1  "/usr/local/sbin/mgetty -s 115200" dialup on secure

so based on your comments I added

ttyd2   "/usr/local/sbin/mgetty -s 115200" dialup on secure

and changed the line in /usr/local/etc/mgetty+sendfax/mgetty.config to

port cuaa2

and rebooted, which caused this error:

01/05 09:39:38 yd2  mgetty: experimental test release 1.1.31-Jul24
01/05 09:39:38 yd2  check for lockfiles

such file or directory

I'm unfamiliar with "device.hints" (other than having now read its man 
page), so I'm unsure as to whether this appears to be something that it 
would be able to fix.

That would explain it.

Yeah, it was one of those cases where the page I found when googling 
suggested mgetty, so I just went with that.

I'll keep that in mind, but so far you're well ahead of me as far as 
expertise ;-)
