PSKmail message from rein@xxxxxxxxxxxx Hi Robrt, the default socket for fldigi is 7322. You can try that by doing 'telnet localhost 7322' and see if the socket is active. you can also try: rein@dopey:~$ netstat -a | grep 7322 tcp 0 0 localhost:7322 *:* LISTEN tcp 0 0 localhost:7322 localhost:45935 ESTABLISHED tcp6 0 0 localhost:45935 localhost:7322 ESTABLISHED the communication won't work if there is no socket... By the way, we are now all using the jPSKmail client (0.5.2) and fldigi-3.20.11. 73, Rein PA0R
