[Elecraft] Problem with gmfsk

[R. Kevin Stover]

Hi Lenny.

To fix the ttyS0/1 thing you need to su to the root user and issue this 
command.

*chmod 777 ttyS0*

This changes the device's permissions and allows unprivileged users or 
their programs to access the device, serial ports in this case.

As for Gmfsk itself, it is pretty crude compared to MixW and some others 
but it's the best Linux has to offer for PSK31/MFSK. Believe me, I've 
been down that road, at least Gmfsk works.

Good luck,
