Possible solution if TRX control fails in Mint (invalid configuration)

Normally I run Ubuntu 10.04 where CQRLog 1.5.2 runs as it is supposed to do.
So, just to play around I installed Mint 14 (Nadia) alongside. For some reason I couldn't get TRX control to work.
Starting from terminal (console) I got I/O error. Ofcourse I forgot to make myself a member of the dialout group..
After doing this I still got an error but this time "invalid configuration" when RIGCTLD was starting.
So I checked if I did everything as I thought it should work. Left the radiosettings at "default" and the serialport as /dev/ttyS0. Just as in Ubuntu 10.04. It did not work. Starting from the terminal (console) I still got "Invalid configuration". Hmm, what could be wrong?
Well, I typed "setserial -g /dev/ttyS*" without the quotes. Only to find out that setserial is not a standard command in Mint 14. To solve this I typed "sudo apt-get install setserial" (again, without the quotes). Now, typing "setserial -g /dev/ttyS*" gave an output I had never expected. It turned out that only /dev/ttyS4 and /dev/ttyS5 had a known UART. This while I have only two serial ports on my PC.
Where I mention "typed" I mean, ofcourse, in the terminal (console).
Nevertheless, in CQRLog I changed /dev/ttyS0 to /dev/ttyS4 and all was well!
I am not sure if anyone will ever run into this problem but it may well be of any help if one does.
