Well maybe yours is called HyperTerminal or something. In that case you have it under Accessories/Comunications under your Start Button. Once you have uploaded the cgi script and want to make it readable you should connect to your server in Hyper Terminal and login with your password. Then you write something like this:
chmod 755 portland/cgi-bin/myscript.cgi (or myscript.pl if it is a peral script)I am not sure of the address ocnse you get in on the server. Maybe Portland can provise you with that.
Command chmod 755 makes it readable and chmod 777 makes it writable (I think).
I will try to find a list of usable UNIX commandos for you.
