[HECnet] FreeAXP Alpha Emulator

[Sampsa Laine]

Joe,

In this case it literally is reading from a file descriptor and writing to a socket and vice versa - it's very straight forward.

Mind you, personally I would just configure a couple of ports on my terminal server to do it for me - I guess you dont have one of those lying around...:)

I love it when you systems guys say it's not brain surgery... I'd tend to agree; however, I'm just a dumb electrical engineer turned sys-admin -- any coding experience I *did* have was spent at the microcontroller level where things are simple...

sorry to bother... have a good evening

Hmm...

For 1., I would just hook up getty or something on the linux box and have it automatically connect to the TCP serial port on the VAX.

For 2, not sure, but it's not brain surgery writing something that reads from a /dev/tty* and writes to a TCP socket.

Could probably use the same little bit of code to accomplish both...

1.) hooking a vt up to the host linux box to access the VAX
2.) seeing if I could pass inbound serial data from a [serial] scanner to software on the emulated vax

I know.. sounds silly...

Not much no, AFAIK the serial ports on SIMH VAX just expose themselves to the outside world as a TCP socket (listening inbound only, again as far as I can tell)...

What are you planning on doing?

Already done, my friend... it should be in the latest push... 

Ever done much serial (e.g. RS-232 and the like) programming? If so, do you know of any good references? I'd like to see if I can interface with the serial ports on a simh vax... 

Cheers...

OK,

Cool, you need to let Johnny know so he can update the master node name database as well.

Sampsa,

I'm sure you've already realized via update, but I was just thinking that I forgot to mention it to you -- I've taken area 20 so as to be able to give you back your node addresses. I think I had the 8.50n series...

Also, I have taylor up on solaris 10.. just need to configure it...

Guys/Johnny,

I'm registering two new nodes in my area, BONZO and LEMUR.

BONZO is at 8.800
LEMUR is at 8.430

Have you ever run an Alpha with only 128MB of RAM? That is the absolute
bare minimum I'd run 7.2 in, and it wasn't fun. I really wish they'd allow
between 192MB and 256MB, as at that point it starts being usable. Of course
I'd also like a Linux version. :-)

They have a Linux version called CHARON-AXP/ES40 for Linux NCE. You can find it at http://www.stromasys.ch/axpnce/ .

I've set it up here and it does work. The only downside is that the non-commercial (free) version shuts off after 30 days requiring a restart. Plus, it's time-bombed to stop working after December 31, 2010 (although a newer version should subsequently be available if past history continues).
