It might be that the ttyS0 is in use and the dongle has been moved to ttyS1 or something. A reboot might normalise things.
Incidentally, in the configuration picker, you just needed to pick your configuration...

rebooted multiple times and ran "ps -lt tty0" to see if there were any other processes using the tty and had none running. The tty port does work with the vfd in the debian 6 instance of linuxcnc. Thanks for the suggestion.

You might not have permissions to access it.
try ls -l /dev/ttyS0
You could trybut I don't think it will stay after reboot.
try ls -l /dev/ttyS0
You could try
sudo chmod 666 /dev/ttys0

you're correct about the permissions as it is root access only. Ill try this later today from the root user. thanks

Continuing this thread, I did log in as root user and checked the tty ports and they are not being used by other processes and shown as idle. Here is the message being generated in the linuxcnc_print.text file:

I guess copy the terminal output.. I didn't see any errors listed in what you posted.

Let me say thanks for hanging in there on this and in reading the LinuxCNC documentation, as well as this output message, is it possible the "uspace" is not configured properly?

Don't try to run from the root account. We can fix the permissions of /dev/ttys0 so you can access it from the user account

OK, I did change the permissions for /dev/tty and that resolved the starting LinuxCNC issue. I had one more problem with not being able to get out of E Stop. I resolved that by adding" -15-not" to the estop pin in the ini file. I'll run some g-code later today but the original problem seems to corrected. Thank you all for the help.
