Try using more logging, at least temporarily, then you should be able to
see from your ppp.log just what's going on. For about 10 years I used:
set log phase chat connect carrier link ipcp ccp ID0 TUN command

Try /dev/cuaa0. At least in the olden days, cuad0 was configured more
for dialin rather than dialout. This may? explain the next two lines:

Not sure why you don't want to use hardware flow control? Is this with
a regular external modem? Anyway, I've always used ctsrts (with cuaa0).

Looks ok. TIMEOUT 60 is plenty for a dialup modem, but whatever.

You probably don't want both those add statements. Try taking out the
first one, and replacing the last one with the add! default HISADDR.
Unsure if you need an 'enable pap' as well, maybe default. Can't hurt.
Anyway, some extra logging should show you when and how it fails, if it
still does ..
