RSTS does too (for sufficiently recent versions, like V10 or so) -- though the NCP bits don't seem to be there. But there's a driver and it can be told to turn on if you issue the DECnet control syscalls directly. Aha. I think I looked at RSTS/E DECnet SPD only, and didn't find any mention of it, back when I was playing with that. Or perhaps I got the information from somewhere else. Can't remember for certain right now. I wonder why you can't set it from NCP though? Weird if they have the functionality, but no "normal" way of enabling it. On a Pro it even works in synchronous mode (because there the "UART" is actually a USART). I don't think you can set it to synch mode in DECnet, though, so that is more of a theoretical thing. But yes, RSX supports both synch and asynch mode. Johnny
