Automated pserver login to CVS with Perl

[Ross Hammer]

I'm attempting to do a WinNT pserver login with a Perl script. I want 
the script to capture the output of the "CVS login" command.

set CVSROOT=:pserver:address@hidden:C:\cvsroot
CVS login

The above causes a prompt for the password. If I execute the "CSV 
login" command in Perl by opening a pipe, then I can either pipe the 
output or the input, but not both (right?).

Are there environment variables than can be set to get around this? 
Is there simply a better way to do this?

Thanks,
-Ross
