This is very straightforward: you have the ppp locking wrong. Make sure
pppd will create the lock file mgetty is looking for (/var/log/LCK..ttyS2)
*before* it touches the serial device. Most likely, you only need to
specify the "lock" option to pppd.

It's very clear from the log_mg.ttyS2 file.

mgetty waiting for "activity".

There was some activity on the serial port. Is it a dial-in or dial-out?

There is no lock file owned by "someone else", so either the dial-out
process goofed, or it's a dial-in. Mgetty locks the device, to make sure
all dial-out processes know the port is in use.

This should never happen, so it's likely the dialout process is pppd and
has changed the line discipline.

Waiting for RING will - naturally - fail as there is data going out, not
coming in. And so on.
