Hi, I just started studying for my BCRAN and came across Async character stream calls. Can anyone point me to a URL on how async technology works and how is it differnt from synchronous calls like ISDN initiated calls? also, how an async initiated call flows and make a successful connection at the access server? Thanks Dinesh. __________________________________________________ Do You Yahoo!? >From homework help to love advice, Yahoo!
