Hi Nikos
That is fantastic news indeed.
Hopefully once U get the serial port working, you will be able to tell us all that the G8JCFSDR can be got to operate under LINUX
To help check your serial port connectivity, if U open a terminal emulator to the port, baud rate 115200, 8data, 1Stop, No Parity, Line terminator CRLF, U can issue the command
v<crlf> and the SDR Shield will respond with the version number
f nnnnnn<crlf> where nnnnnn is the frequency in Hz to set the tuned frequency to will tune the SDR shield
f ?<crlf>? and the SDR Shield will respond with the current tuned frequency
