i downloaded vnc .. didnt know it was free .. so i can play around with it :)

the computer i have to connect to i have to reach via dial up ... 'pc anywhere' will accept the dial up on the other side .. i cant use 'external connection' of windows to connect to the computer as i dont know how to specify the username/password/... as it was handled by 'pc anywhere'

how can i create a dial up connection with VNC ?
when i run the VNC server on the remote computer .. can i set it up to accept incoming calls so i can connect to it from my pc at the office via dial up ?
