PPP and callback

PPP and callback

Post by Jim Donne » Fri, 14 Mar 1997 04:00:00



I know this question isn't exactly ".linux.networking", but I hoped someone
with an answer might be reading this group.

I have a Linux box at work configured as a PPP server which calls
people back when they dial in from home.  If the remote machine is
running Linux as well, the whole connection process works nicely
with the "callback" version of the "ppp-on-dialer" script.

Dialling in from Windows 95 also works, except that I haven't found any
way to make Windows 95 accept the callback.  Although various connect
scripting facilities are available, none of these work because as soon
as the remote modem disconnects to do the callback, the Windows Dial Up
Networking connect process aborts.

It feels like this should be an easy problem to solve, but I'm out of ideas.
Can anyone help?

Thanks,
Jim

I have exactly the same poblem and I'm very interested in a solution,
if there is any.

Thanks

It is if you how. I use the same setup from home. I can't give you the
detalis now, but I can give you some hints.

First you need to installe the dial-up scripting, this will help you
login on.

If you go to the modem settings you need a few "extra settings" which
I don' t remeber. But you need to tell the modem NOT pass the fact
that the other end hung up. I got this from
http://www.windows95.com/connect/dialback.html

Put this in the extra setting
&C0 S0=1

for me this was not enough I also needed somthing like &S0 I think it
is the data set ready option that need to fixed.

Please send me note telling me how things are workiung out. I can mail
you my exact setup if you need it

cheers
Lars

I checked on my news server, and there are six
comp.os.ms-windows.networking.* newsgroups, any one of which might get
you a more authoritative answer than this newsgroup.  This is not
intended as a flame, but I really think you would have better luck
elsewhere.

In a rather different context (not Windows, not Linux, not PPP) I've
hit the same problem.  I got arround it by using the "AT&S&C" command
to force the modem DCD and DSR lines to stay high even during the
disconnect.  Once the ring-back had completed I re-enabled honest
reporting of DCD and DSR by the modem.

In a perfect world this is true, and inedead I'm breaking my own rules
by answering an off-topic question.  The trouble is, the smart people
hang-out in in comp.os.linux :-)

There is a solution:
use the string "&C0&D0&S0S0=1" in the DUN-config.
