I could just use an old fashioned RS232 switch box, but I was looking for something better. For one thing, a smart switch that would actually buffer output from the unselected ports would be nice, and it d be nice to be able to change the selected port from the terminal keyboard. What d be idea is something like the multi session support that some of the later VTxxx terminals had, but with multiple physical ports and without any special host software. It d also be nice if I wasn t limited to just one physical console but I could use any terminal anywhere on the network too. I thought about using a DECserver in reverse LAT for this, but AFAIK the only way to connect to a DECserver in reverse is from a real host system, like VMS or RSX. That means my console terminal would have to connect to a VAX, log in, and from there connect out again to the DECserver and the PDP-11 or 8 console port. Kinda complicated and ugly. With reverse LAT enabled, you can connect to the ports from an attached terminal. I currently forget how, but it wasn't very hard. It's how I tested having VMS 1.50 on my VT420. I don t think there s any way to have one terminal server connect directly to another terminal server w/o a host system in between, at least not with LAT. Telnet would be OK, if anybody can recommend a multi-port telnet terminal server that works in reverse. It d be especially cool if it can telnet to itself then I could just connect directly from one port on the server to another. Anyway, I was thinking that I can t be the only collector with a bunch of computers and room for only one console, so I thought I d ask what other people are using.
