I had this RPG/400 developer working for me, who after using Telnet for the first time to connect to one AS/400 from another became stumped by how to end his Telnet session. After looking up various TCP/IP commands on the system, he plumped for ENDTCP *IMMED. Every single user on the system was instantly kicked off! He never quite lived that one down! Where do you want to go next?
