making buffalo wlar-l11-m modem dial

I've aquired a wlar-l11-m buffalo airstation access point with a built
in modem. I have managed to conect to its ip (192.168.0.1) with my web
browser and configure my dial up settings but what I can't get it to
do is make it dial up to the internet with it's modem.

I have tried all three of windows 98 internet options, never dial,
dial when network conection is not present and always dial but the
best I can do is get the access point to flash its recieving traffic
when I ask for a web site but not dial out.

I don't know I there is some other way to connect to it or some
command that could trigger the modem. The webpage configuration screen
does has a button to "disconnect line" but nothing to connect. I've
told it to accept connections from my computer's mac address but just
can't seem to trigger it...

Any ideas very welcome.

Thank-you
