Acceso telefonico a redes desde VFP

Mmm lo siento, nunca he hecho algo asi, y lo unico que pude conseguir es un ejemplo de RAS para VB, te lo paso, a ver si lo puedes traducir a vfp.
'This program let you dial to your dial-up connections using whether
'the stored user name and password or the ones you specifies
