I've used Terminal as my Telnet application for Packet Cluster for many years now. Recently however, I'm encountering a form of a "dead session" phenomena that has me stumped. Recently, the site VE7CC has become one of those "dead session" sites for me. Specifically: telnet dxc.ve7cc.net (my command) Trying 22.214.171.124... Connected to dxc.ve7cc.net. Escape character is '^]'. *** Connected to VE7CC-1: Greetings from the VE7CC-1 cluster. Located near Vancouver BC Running CC Cluster software version 3.101c Yet, at the point where I enter my call, the session become INOP. Terminal itself does not think the session is closed, however. However, if Terminal is launched through a link on a web page as found on bcdxc.org, my login is successful and DX spots flow. The line of code within the bcdxc.org web page is: "telnet://dxc.ve7cc.net:23" (no surprises here) Of course, I have also tried starting a Telnet session with port 23 specified without success. I am guessing that something is different in the Terminal environment when launched from Safari, but I can't guess what. OS 10.11.6 Thanks in advance!
