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. On a Pro it even works in synchronous mode (because there the "UART" is actually a USART). paul
