Re: Question about connecting from Cisco/Sparcstation
It doesn't look like the Sparcstation 1 has jumpers on the motherboard to set the serial ports to RS423... but I also have a Sparcstation 4 and a 10 so I guess I'll just use one of those instead. Thanks!

Some Sparc serial ports can be set to RS423. I think you might get lucky with the SparcStation 1; and further assuming it’s similar to the 4 or 5; they could. ?
Hello everyone,
I'd like to connect my old Sparcstation 1 to Telebahn. I've got a Cisco 1841 with a WIC-2T, can I use a?CAB-SS-530MT cable to connect the WIC-2T directly to the serial port on the Sparcstation? And then run Sunlink on the Sparc to connect to Telebahn??
Btw my dad worked for Telenet back in the 80's and when I told him about this project, he said "why would anybody want to do that?"??

Hi folks,
sorry for the late notice:? This Saturday is another TELEBAHN Saturday, and I'll be carrying my X.25 gear to the which takes place on the weekend in Dietzenbach.? If you have the chance, I'd appreciate it if you could bring up some of your TELEBAHN gear so that visitors have a chance to feel the lag. :)
As a reminder, my systems are:
23000100 cisco 23000200 VAX 4000/105A running VMS 5.5 23000300 SPARCstation IPC running SunOS 4.1.4
Cheers, Hans

I’d recommend reading the Wikipedia articles on x.25, x.28, and x.3 as they may help.
Briefly, and hopefully I get all this right! ?…
X.25 defines a layer 3 encapsulation, like IP, but as I understand, the destination address in an X.25 packet is only significant to the interface on which it is received.?
X.28 defines the operation of the PAD, or packet assembler/disassembler. ?This is just a term of art for something more commonly known in the TCP/IP world as a terminal server. This standard defines things like how the PAD operates, the prompts it presents the user, the commands it accepts from the user.
X.29 is the encapsulation for a “call” over x.25 and is analogous to telnet over TCP.
X.3 is a set of characteristics sent between the endpoints of an x.29 call and is analogous to telnet options, like if the call is character or line buffered, who (if anyone) should echo too the caller, etc.
Xotpad performs all of these things entirely in software, and encapsulates the x.25 packet in TCP (aka XOT), where the distant end will de-encapsulate and process the x.25 packet.
A Cisco can do XOT, but can also do LAPB, which is the native layer 2 encapsulation used for x.25 packets over serial interfaces.
I recommend xotpad and wireshark because it may be easier to start simple, inspect the packets, and understand how the protocol works a bit before involving things that are a little harder to troubleshoot. ?That said, the Cisco implementation is decades old and has seen a lot of use, so is pretty robust.

I'd not want to connect a host through a PAD, but it would be kind of nice to have one for connecting terminals or modems :)

I’ll give a call to your IPX tomorrow - I’m personally partial to native x.25 implementations vs an external pad anyways.
That said, I would like to see an old Tymnet engine in operation.

Then, you can try out calling some x.25 hosts per the community doc here:
If you are eager to see the protocol, wireshark will dissect it.
Also in that doc are some Cisco IOS configuration examples.
You don’t actually need to use the serial interface at all to get started.? You could configure the Cisco Ethernet with dhcp or static, then with the x25 route that specifies xot (search for x25 route) in that doc, you could just use the x28 pad in the Cisco to make your calls.? The command to get into the pad, as I recall is “x28”.
One destination from that doc that has been working recently is “40400201”.
?I dont have a WIC-2A/S but I do have a WIC-1T. Of course without the cables but, maybe I will buy some in the future. Could I use the WIC-1AM-V2 and WIC-1T together? Also I dont think I have a machine with a synchronous serial interface, I didnt know I needed one.

Do you have a machine with a synchronous serial interface and suitable X.25 software?? Or do you want to just connect your two cisco's with X.25?? Your WIC-1AM-V2 is a modem and will probably not be very useful.? You'll need synchronous interfaces like WIC-2A/S and the correct cables for your application.? Given?that there is a wide variety of X.25 products, there is no all-encompassing "getting started" guide, but we'll probably be able to help you if you have questions and the stuff that you have is not too exotic.
Hey, I am also a clueless guy who has never used X.25. I have 2 Cisco 2620s, one of them (that I want to use) has a serial addon and a WIC-1AM-V2 addon that I wish to use but I dont really know how and I dont know what it can do with X.25.
Is there some guide to how i can set it all up?

Years ago, the MajorBBS (and later Worldgroup) supported x.25 with the PC XNet card from OST.

I’ve not found an example of the ISA card, but what I do have is the headers for the DOS device driver and the MajorBBS kernel with x.25 support.
I’ve been working to implement the DOS device driver in a fork of DosBox-staging with the intention to implement a thread to accept XOT connections and translate them to relevant API call results. ?So far, I do have MajorBBS believing it has found the card, and trying to poll it for packets.?
Anyways, if this is interesting to anyone and/or if anyone has interest to hack on this too, let me know!

Hi,
just so you know:? I'm switching off my TELEBAHN gear for three weeks while I am traveling abroad.? Things will be back online in late August, probably on a schedule.
Cheers,
