The umask makes it so only root can read the files created by the script
and its called commands. I gather you're talking about the ppp-connect
script? There's a copy of the chat script made on the fly. As it might
contain passwords, only root should be able to see it.

I might have misunderstood you before. I thought you were trying to
set ppp parameters from an stty command.

The stty in ppp-connect is for chat to work right. chat (not ppp) needs
to be able to talk to the modem w/o waiting for the carrier to be
present. I'm not sure if that stty is needed, but it is only setting
things for the life of the dialing process.

While ppp is running, try "stty -e -f /dev/tty00" and see what the
settings are while ppp is up.

The serial drivers will certainly respect CTS going low if crtscts is
asserted. They will immediately stop sending (any character in
transmission will of course be finished).

One other question. Are you using the modem initialization string you
use inder MacOS? The modem string in the non-demand-dial kit is just
the one MacSlIP was using on my modem. Your modem might need different.

Take care,
