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.
