You don't need to dial. You are talking through the serial port the moment
you start minicom. Since nothing happens that means the other end isn't
talking to you. You can turn on Local Echo if you want to see minicom show
you what is being sent.
Don't dial. Dialing is only for modems. Also, try other speeds. Are you sure
you have the right serial port and don't need a null modem? Do you have any
documentation for the thing?

Hmm, UART unknown? Why do you have skip_test enabled? That means the kernel
won't even verify there is a valid serial port there. You are sure that it's
ttyS0 not ttyS1?
