In 10.10 and some earlier versions its

While there is no specific test for these ports, last week I ran this on my
computer and one of the tests checked my USB ports and I believe it wanted
to check a parallel port. I have nothing to connect to the parallel port
and have no serial port.

I recently rebuilt my system from the ground up using Ubuntu 12.04. I installed
my same files I had on 11 including cqrlog. I have been unable to conrol my
radio throigh the com 1 port. I suspect it may not be tty0 or 1. I tried the
terminal command dmesg | grep tty but it returns nothing.

Use these commands:
cd Desktop
sudo lshw -html > config.htm

Then open config.htm in your browser, search for "serial."

I still keep an analog external FAXmodem configured: My first serial port is
/dev/ttyS0. (Last two characters are UPPER CASE "S", and zero.)

I had a bit of additional debugging to do with my 12.04 installation (efax-gtk)
as well.

I recently installed Ubuntu 12.04 from the ground up, I had been using 11.10. I
installed my applications, mainly ham radio programs such as cqrlog and fldigi,
but cannot get them to communicate with my radio or any serial device.

I tried dmesg | grep tty but nothing is returned. I tried "setserial -g
/dev/ttyS[0123]" but permission is denied.

I have a suspicion that my serial port are not active. My system has a standard
com 1 serial port under Windows and was tty0 under 11.10.

I seem to be lost with 12.04.

I will tell you what might be the problem but don't know how to fix it
other than the rules.d folder, (that I have problems defining rules in).

Try starting your applications as root from the terminal. I have an AVR
programmer that I can't get to talk to the USB ports any other way,
because it is not in a group that has permissions. Because I don't
understand how to set-up rules in the rules.d files I only use the
programmer as root started from the terminal.

If you can start your applications from the terminal as root, I bet Roy
can tell us how to establish rules and groups that will not be the
headaches that I got trying.
