The irony of history. LAT and DECservers were invented so that machines no longer would need to have local ports. Now you are using LAT and DECservers to access machine local ports. :-) Yes. I know what you mean, and what you want to do. However, DEC did definitely not envisage that. Their intention was the exact opposite. All that said, it is mostly doable under VMS, but it requires that you write some software yourself. It might be that someone have already done so. It might be worth searching through old DECUS libraries...

Doesn't mean it wouldn't be a nice feature to have :) Sampsa On 11 Jun 2010, at 01:36, Johnny Billquist wrote: What pays to remember is that once you had LAT and DECservers, you didn't use serial ports on your VAX anymore, especially not on a site where you had several VAXen. You *obviously* had DECservers if you were using LAT, and you *obviously* wanted to put the modem on the DECserver if you had one, and *especially* if you wanted to access the modem from several machines. So yes, it's an obvious idea, and it had an obvious answer. It's just you who are trying to do things backwards... :-) Johnny
