Not sure what is going on there. Personally I'd get the ports working
first, then worry about connecting other stuff. Which is pretty much
what you started below:

I assume hal_par_port is a typo, it should be hal_parport.
But the real problem is "0x0378". You have it right up above, it should
be "cfg="0x0378". Any info passed to a module when you loadrt it is
always of the form <some-name>=<some-value>.
Another problem - when you are running EMC, it creates realtime threads.
When running standalone with halrun, it doesn't, and you need to do it
yourself. Add these lines:
loadrt threads name1=foo period1=1000000
addf parport.read-all foo
addf parport.write-all foo
start
The first line creates a realtime thread. The next two add the parport
code to the thread, and the last one starts the realtime code running.
Then continue with the commands below

As I mentioned above, try with cfg="0x0378" and it should work. To load
the driver for both parports at the same time, use
loadrt hal_parport cff="0x0378 0xdff0"
