Is it possible to set a computer to connect to the internet at prearranged times

[jessiedog]

My dial up takes an age to download security each day and I was wondering if I could set up to connect at say 2am each day so that it is ready in the morning.

May thanks

Literally a dial up modem? Do you enter details or does it do it all for you
