My setup for /etc/ttys is:

# Serial terminals
# The 'dialup' keyword identifies dialin lines to login, fingerd etc.
# Mgetty lines - replace dialup getty
cuaa0   "/usr/local/sbin/mgetty"        unknown on insecure
cuaa1   "/usr/local/sbin/mgetty"        unknown on insecure
ttyd0   "/usr/libexec/getty std.115200" dialup  off
ttyd1   "/usr/libexec/getty std.115200" dialup  off
ttyd2   "/usr/libexec/getty std.115200" dialup  off
ttyd3   "/usr/libexec/getty std.115200" dialup  off

Note that the mgetty is using cuaa0/cuaa1 instead of ttyd0/ttyd1.
I'm not sure if this made a different for me, but this is how
mgetty installed by default.
In my case I set the speed in the mgetty configuration file.

The number is automatic, just "pseudo-device	tun" should be sufficient.

It looks fine.
Does it work for you?

> Is the "set ifaddr ...." line rigth ?

Does it work when you test it?

You may be able to get up to 33600 both ways with analog lines but no more.
For 56k operation one end must be digital.  In that case downstream is 56k and upstream is 33600 (max)
