Lines: 17 By the time the end of 1982 rolled around, there was not supposed to be any bridging at all. Link 0 was supposed to be shut off on all IMPs forbidding NCP traffic at all. There were a few people granted dispensations, and it is easy to see that you'd only need a host with both NCP and TCP/IP to make a mail gateway, but I don't recall that any officially existed. I'm sure nothing automatic was done for FTP, and telnet was loosely supported as the TAC's were able to initiated both NCP and TCP telnet sessions for quite some time after the changeover (probably only deleted to get the code space back to implement tacacs). Fortunately this was the last Jan 1 protocol change after much griping by people who blew a couple of Christmas holidays. First on the long leaders conversion and then on TCP. -Ron
