Parallel Port Tester

Yes. Have just this moment installed Mint 20 and now going to follow procedure to install.

Thanks will keep you updated

That is Linuxcnc now running on Mint 20 which was no bother to install following instructions. Unfortunately I still can not get ptest to work as it still cant find port. Ahead but no further forward.

If your pc only has 1 parallel port, have you tried just using the line
Or if you have 2 ports you might need to useto access the "other" port.

What does the following command show at a command line?

Only have one parallel port

~$ loadrt hal_parport cfg="0"
bash: loadrt: command not found
hamish@hamish-HP-500B-Microtower:~$ sudo loadrt hal_parport cfg="0"
[sudo] password for hamish:
sudo: loadrt: command not found
hamish@hamish-HP-500B-Microtower:~$ cat /proc/ioports |grep parport
hamish@hamish-HP-500B-Microtower:~$

Looks like I have a problem with commands. Will look in "packages"?

I have reinstalled Mint 20 and have as yet to install cnc. From lspci -v I get

03:04.0 Parallel controller: Device 1c00:2170 (rev 0f) (prog-if 01 [BiDir])
Subsystem: Device 1c00:2170
Flags: medium devsel, IRQ 10
I/O ports at ec00
I/O ports at e880
Which suggest there is a parport.
Will try later today. Thanks

I cleaned system out and installed Mint 20 Ulyana along with 2.8test, which appear ok. Latency test has come down but appears a bit high.
I have run the parport tester but it still fails to find port with
Note: Using POSIX realtime
config string '0xec00 out'
Linux parallel port @60416 not found
When I run lspci - vv I get

Does this suggest I do have a parport?
Thanks for help

When I used"0 out" I now get
