While a lot of you are getting in a frenzy with the WIN/3B TCP/IP Ethernet stuff, I felt it was necessary to pose a few questions to the net on STARLAN. STARLAN boards for those who are interested should still be available from Robert Slaski, and I recommend them very much. Granted not too many machines (especially non-AT&T ones) run STARLAN, and worst yet, the 1Mbps STARLAN, as opposed to the 10Mbps (aka STARLAN-10). Documentation on STARLAN is the pits, even the programmers manual only goes into the high-level library calls found in the libslan.a library. While perusing the /usr/include/net and /usr/include/net/sys directories on my system I started to get some ideas about doing "low-level" STARLAN operations, and possibly learn a little more about this network media I have on my two UNIX pc's. The STARLAN driver on the UNIX pc has a special implementation of streams. What modules can be pushed (I_PUSH) on to the /dev/starlan stream? The URP protocol (what it uses to communicate between machines, similar to what Ethernet can use, TCP/IP) is a stream module. Does anyone have documentation on how to use the low-level driver ioctl()'s as well as the stream driver. Doing a "strings" of my uucico (HDB) reveals some interesting items... These stream modules -- what do they do? How do I use them? slancall: push(ccmod) errno %d slancall: push(urpmod) errno %d slancall: push(psxmod) errno %d In /usr/include/net/starlan.h, there are some interesting #defines ... #define LIS_PROMISC 0x0001 /* Promiscuous listening */ (One could write some sort of thing to listen on the network and catch all the network packets in promiscous mode?) #define ENC_MANCH 0x0004 /* Manchester encoding */ #define ENC_NRZ 0x0000 /* NRZ encoding */ (Encoding methods?

I can trade a little info here ... Intel sells a package with (two each) starlan chips, transformers, blank circuit cards and instructions for about $65. The cards use an XT bus, and there is some MSDOS software for playing with them. I have the kit, and I'm seriously considering scoring a used XT motherboard and power supply for use in a slave controller. I'm figuring a remopte print spooler, thermostat furnace control, etc, all out of an PC mounted on a piece of plywood in the phone closet. Now, for that little tidbit, I have a question. What do I have to do to get cu to work with this stuff? uucp works fine over starlan, but cu just hangs and times out after connectung to pc_uucp at the other end of the line. I installed the starlan software and HDB via the install program, and the starlan documentation doesn't mention cu at all. (nor does the HDB docs mention starlan). Does anybody have HDB and starlan working together in all ways? ################################# :alex. #Disclamer: Anyone who agrees # Systems Programmer #with me deserves what they get.# University of Maryland Baltimore County ################################# alex@umbc3.umbc.edu

I'll jump right in and pose another. I'm ashamedly ignorant about these network protocols, so maybe someone with a tad more knowledge could answer this question: Can I use the STARLAN board to connect an X terminal to my 3b1? I'll be starting on an X port to the 3b1 Real Soon Now if this can be done. As usual, thanks in advance. -brad -- ...!emory!stiatl!slammer!brad ...!gatech!bagend!slammer!brad (Brad Isley)

Do you have the AT&T Starlan Network Application Programmers Reference Manual (999-300-208IS)? It comes with some sample programs for both unix and dos that run on top of either the URP or OSI protocols. Also, DOS kermit, versions 2.9 and up, will connect over starlan (to each other for file xfer, and to unix hosts for terminal emulation). This also works with either version of the DOS starlan software. Too bad the OSI version was never done for the 3b1. Les Mikesell les@chinet.chi.il.us
