Writing dialup software in VB

I wish to write a software in VB4 or VB5 which will dial a perticular phone number thrrough modem and upon a connection make, it should send username and password to the number being called and establish a PPP connection.

I can very well use an existing dialup adapter in 95, but I cannot have a control to check whether a healthy connection is done or not ,, or username & password are accepted or not.. so that on that basis, I wish to fire different different applications.
All this is in context with a local ISP , to which when the client connects, he must give username & password in order to get through..

OR,, is there any OCX to carry out PPP dialing and get the required events.. or I should use Com port control ocx which is present there in VB4 or VB5..

Thanx in advance
