Running stock RH5.2, kernel 2.2.2, using the script provided to get a
ppp connection going using a standard 28.8 modem . . . it will take
anywhere from 5 sec to 45 sec for the dialing to start after you execute
the script . . . command line is:
. /etc/sysconfig/network-scripts/ifup-ppp daemon ifcfg-ppp0 &
pppd comes up right away w/options, but chat takes a long time to start
. . .
attached are ifup-ppp, ifcfg-ppp0, chat-ppp0
anyone know where the delay is coming from? thanks :-)
