[Elecraft] Problem with gmfsk

[w2bvh]

Hi

After lots of hard work I've got Fedora 3 downloaded and running. I've 
also got gmfsk downloaded and sort of running. It receives fine, but I 
have some trouble with transmit.

When either tty device (ttys0, ttys1) is selected to control the ptt, I 
get a message box that says permission is denied for the device. Does 
anyone know how to get permission for these tty's in a user (as opposed 
to root) logon?

Also, gmfsk is sort of 1 generation older than the current Digipan and 
Hamscope offerings for Windows (to say nothing of MixW). Is there a more 
up to date psk31 / mfsk program available for Linux ?

Thanks in advance for any help.
