   FYI, I tried removing the comments around O_NDELAY and my ppp login
script, included below, no longer works. This message is logged:

Sep 19 19:58:10 wheel pppd[99]: could not set up connection

And here is the script:


exec pppd defaultroute connect 'chat -f /etc/ppp/totiac' lock passive noipdefault mru 296 mtu 296 tty02 19200 > /dev/null 2>&1

   Removing O_NDELAY got rid of the problem. Perhaps a change to chat would
be required?
