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
loadrt hal_parport cfg="0"

Or if you have 2 ports you might need to use
loadrt hal_parport cfg="1"
to access the "other" port.

What does the following command show at a command line?
cat /proc/ioports |grep parport

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"?

That means no parallel port !
Did you try lspci -v on Mint 20?

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
03:04.0 Parallel controller: Device 1c00:2170 (rev 0f) (prog-if 01 [BiDir])

Region 1: I/O ports at e880

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

config string '0xec00 out'

Region 0: I/O ports at ec00
Region 1: I/O ports at e880

try
'0 out'
instead of the port address, then if that does not work try
config string '0xe880 out'
Restart the PC between tries.
