I created the async DDCMP driver when I was doing the (unreleased) PRO port for RSTS (9.6 originally). I handed it to RSTS development, and they integrated it into the release. But I personally never did the NCP work. Probably because it wasn't familiar code and it would have been a lot of work. Instead, I just wrote a little 10 line utility to issue the line on/off syscalls to the kernel. Way fun, and impressive. Thanks for that piece of information and history. I guess they didn't see much need of DDCMP support in RSTS/E at that point. How did you select which serial port it would use, by the way? Or was this only done for the PRO? Hmm, I guess it could have been passed in in the syscall... Johnny> I don't think you can set it to synch mode in DECnet, though, Johnny> so that is more of a theoretical thing. But yes, RSX Johnny> supports both synch and asynch mode. What I meant is that I did synch mode, including for DECnet, in RSTS. Ok. I misunderstood you. While you can use the serial port for DDCMP DECnet under P/OS, I don't think you can set it to synch mode there. Even though the hardware supports it. But for code that you wrote, obviously you could take advantage of all the possibilities. :-) Johnny
