Yes, along with `transport input pad` if it's not currently set to include that.

(And probably something like `modem CallOut` to have the ESP32 notice when the call is lost and trigger some kind of logout/reset... Yesterday I was trying to get `modem callout` working for the AUX line, so that doing a `logout` on the connected Linux system also drops the X.25 call, but can't get the opposite working – Linux seems to ignore DSR so ttyS0 remains logged in even after the call is lost; doesn't help that the IOS that I currently have keeps crashing the whole router if CallOut mode is set.)

It is, yes.
So what you are suggesting, if I read correctly, would be:

a) plug a serial device (computer or whatever) on to the AUX port of the Cisco router
b) configure x25 routing on the Cisco so that incoming X.25 connections via XOT go to the AUX port
If you mean running actual X.25 communications software on the CP/M – I don't think that'll quite work, as IOS will not let you route X.25 over async lines; I believe it only works over synchronous serial ports. (The cpm-x25 docs mention synchronous mode being required on its end, too.)

Though if all you have is an async AUX, you can still connect devices over it, but you'll need the Cisco router *itself* to accept the X.25 call into one of its vty lines (service pad from-xot), and have that line configured with an `autocommand` to telnet somewhere further.

(E.g. if the device provides a plain login prompt via serial, then an autocommand to telnet to the router's own "reverse telnet" ports for the AUX line. If the device does PPP, *that* can run over AUX and you can have an autocommand to telnet to the device via PPP, or DECnet `lat` connection, or something such.)
About what you said earlier about not giving users access: In IOS, lines *won't* have console (Exec) access if an `autocommand` is set on them. So it should be safe to assign a few vty lines to `transport input pad`, give them an X.25 sub-address using `rotary XX`, and point them wherever is needed. It's not exactly a pure conversion but it does the job...
Ahhhh. Hold on. I completely forgot about an easier possibility, even though I was making my own notes on this *literally two days ago.*

You don't need an autocommand or "reverse telnet" for X.25-to-AUX. You can just directly assign `rotary` to the aux line, and the router will accept PAD calls and directly connect them to the AUX output.

Sorry for forgetting that option.

(From what I understand, that's how actual "PADs" used to work – they'd accept the X.25 call on behalf of whatever async lines they had.)

Though the full "enterprise" IOS images might have more capabilities there; I still haven't installed the RAM upgrades to try it out.

Just reread your post, I think I misunderstood it the first time around.

The AUX port on the Cisco is just an async serial port, right? So what you are suggesting, if I read correctly, would be:

a) plug a serial device (computer or whatever) on to the AUX port of the Cisco router
b) configure x25 routing on the Cisco so that incoming X.25 connections via XOT go to the AUX port

Would this be correct?

If so, that would allow me to join TELEBAHN quite easily :) I guess the computer to connect could be an ESP32 running a CP/M emulator, there must be software from that era available.

Re: TELEBAHN Saturday

 

Greetings,

This sounds like a great idea to me! I do not currently have any
equipment up and running using x.25, but I do have some equipment
which I believe would be suitable for experimenting with it. I leave
that equipment powered off most of the time for energy cost/waste
reasons, but having a set weekly time for people to power things up to
play with is motivating me to set things up and get them working with
Telebahn.

I will be traveling for the next ~3 weeks and not available to work on
this, but after that I'm sure I'll have some setup questions for the
group.

Cheers,
Rusty D.

Hi Folks,

Andrew (ajk) and myself have been thinking that it would be nice to have a recurring time where we bring our systems up and play around with some of the other X.25 nodes. Maybe some of you are interested in joining us? I would propose that we declare the last Saturday of a month to be "TELEBAHN Saturday" - My machines will be running all day, and Andrew said he'll run his around midday US Central time.

I've set up my VAX so that you can create yourself an account and then use the SEND command to chat - Connect to 23000200 using xotpad or your node's native PAD and set yourself up for Saturday.

Hope to meet some of you and some of your machines on Saturday!
