Some parts possibly, but it would be very complex. Much of the actual TCP/IP implementation is in the form of device drivers. In RSX, there is (now) IF:, which is the basic device interfaces, IP:, which talks raw IP (and ICMP), UD:, which talks UDP, and TC:, which talks TCP. The TC: driver, as well as the UD: driver internally then talks to the IP: driver. The IP: driver in turn talks to the appropriate IF: driver, depending on the routing tables. TC: even understands file specifications, so you can do things like: PIP TI:=TC:"130.238.19.212";17, which will give you the quote of the day on your terminal (that's what port 17 is). (Try it on MIM:: :-) ) Device drivers are very different in the different OSes, so the basic code that deals with the protocol bits can pretty much be used straight off, but all the code dealing with the interfacing to the OS, memory, other drivers, and user applications, will be totally different. I'm not sure exactly how a device driver in RSTS/E works. Also, for ethernet, I make use of a feature in RSX called an ACP, which is like a user level program that extends the functionality of a device. So the ethernet device is an ACP attached to the IF: driver (for the specific unit), and which in turn implements all the logic of communicating over ethernet, including ARP. And then of course, is the tools, which are perhaps a bit more OS specific, but they are smaller and simpler for the most part. Applications (if everything else was ported) would probably work without any changes. Johnny On 2012-04-13 14:55, Steve Davidson wrote: Johnny, Could it be ported to RSTS/E V10.1?

I just thought I'd stir some interest and just general noise by announcing that I've written a small web-server running under RSX. It's written in BASIC+2, and uses the TCP/IP stack for RSX that I've also written. There are probably a bunch of bugs and issues still around, so I'm happy to take any bug reports, comments or whatever. The url is http://madame.update.uu.se/, and if anyone is curious about the code, it's at mim.update.uu.se (same machine, other IP), under MIM::DU:[HTTPD]WWW.B2S (also on HECnet) If people have any interest in this stuff, or something else/more, I'm interested in hearing about it. The TCP/IP stack will eventually (soon) be available for others to download and use, and apart from the web server, I've also written a telnet client, and a few small services under TCP, as well as some tools for administration. I have some polishing to do, I need to finish a DNS resolved, and I'd like to also finish FTP and a telnet server, but I might be open to distributing things before I've finished all those things, especially if someone is interested in helping writing stuff. I have interfaces completed for BASIC+2, PDP-11 C, Macro-11. FORTRAN 77 should also work, but I haven't tried it yet. This all runs under RSX-11M-PLUS V4.6, but I think it should be possible to get running under almost any M+ version, but there might be some hacking needed for some versions. It will not work under 11M, and I never expect it to. One or two drivers as well as one or two tools really are big enough that I need to use the split I/D space feature in M+. Rewriting stuff to not need that is way too much work.
