Simple IP port questions

I'm fairly inexperienced on the IP side of life and have a couple questions.

1). Can ports (80, 21, etc) be enabled 'manually' on a workstation or
server?
2). Is there a Windows command that can be used to manually detect if a port
is open? I know I can use the 'telnet port xx' command to try to connect to
a port (assuming the telnet service is enabled).

Thanks,
Tom
