PPP / Chat wows

[Steven Curren]

Dear all,

I am hoping that someone on this list may be able to provide some assistance
with diald.

I am using mandrake 8.0 and trying to setup a ppp dialup router/gateway.
However, I seem unable to get the chat script working correctly. I seems as
though the expect/send pairs are sending invalid characters.

Have setup the files as below and running (as root) "pppd call blue_sky",
but on each case of sending something to the modem (as seen in "tail
/var/log/messages" below) an alarm is generated. I note that the modem Data
Terminal Ready lights up, but as diald errors out before the dial string is
encountered the modem does not dial.

I have tested the modem with minicom on /dev/ttyS2 and pasted the modem
sequences (ie ATZ) and on each occassion the modem responds with OK. But
when calling from chat script it errors out.

I know that the modem functions correctly with linux, having used it with
smoothwall.

Any advice or assistance would be very welcome and appreciated.

Regards,

Steve Curren
