Neither. It means that pppd is starting up at your end while a login
process is still running at the other end, echoing everything while it
waits for what it needs to complete the login. The login process is
expecting test and so is stripping the eighth bit. Dial in with minicom
and work through the login process by hand to find out what your ISP wants.

Use pppconfig to set it up for dial-out and then use pon to start ppp and
poff to stop it.

Dial-in and dial-out are completely independent. Use mgetty with AUTOPPP
for dial-in.

It contains pppd options that are only read when the connection is made via
that particular serial port.

Either, though it is usually used for dial-in. You need not be concerned
with it, though. Leave it alone.

/etc/ppp/options is read whenever pppd starts up. It should contain
options that apply to all connections. They can be overrridden by options
from other sources. Don't change it.
