Running System Commands on NT, how do i gain a persistent connection with the prompt?

PHP4.0.4pl1, Apache 1.3.12 on Windows2000: Hi all, I am trying to run ANT, CVS and a few other command line utils from a PHP web wrapper, the problem is for programs like CVS, there is a login, in other words: from the prompt: "cvs login <username>" cvs returns a request for the password, now, how do i open the above command in a way that allows me to enter the password and continue on, reading and writing to the same 'shell instance' more or less, basiclly the problem is that I cannot get the excuting script to see me as real user rather than some nobody at localhost, if I could make php/apache run as a specific user with all their permission etc, that would be great and i wouldnt need a persisnt prompt...any help out there? p.s. obviously the win 'runas' command also requires a password so same question there... thanks -Ike
