chat talk to its stdin and stdout but it will not work stand-alone, as in: chat "" ATZ OK </dev/modem >/dev/modem because the line disipline and buffering need to be set. pppd does this before calling chat. calling chat as above will fail on any machine, in despite of working modem etc. The call will hang (can be interrupted with ^C). bye, Peter -- The Toronto Linux Users Group.
