dialin and callback

[marmango <marmango@softhome.net>]

I've been trying to dial into a MS-Windows2000 server, which is set up
with callback.
I've the following section in ppp.conf and it works to the point where
the server calls back, but my modem is not waiting to answer the call.
So, what else should I set to make the same modem (/dev/tty02) answer
the returning call right after successfully completing the dial-in phase?
The calling back server needs chap authentication, so ppp will be needed
to authenticate the dialing-in user.

home-to-KT:
  set device /dev/cua02
  set speed 115200
  set phone 2104651555
  set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-ATX3-OK
ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"
  set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
  add! default HISADDR
  enable dns
  set authname xxxxxx
  set authkey yyyyyy
  set server 7777 zzzzzz
  allow user *
  set timeout 0
  set callback cbcp
  set cbcp 02109345321
