[HECnet] FreeAXP Alpha Emulator

Joe, have a look at this for how to get started with your serial project: http://tldp.org/HOWTO/Text-Terminal-HOWTO-15.html I think for your terminal -> vax session I would setup an account on the Linux box with the shell set to "telnet <simh host> <serial mux telnet port>" For the scanner thing, you probably want the getty to automatically launch netcat - how you get past the VAX login procedures is beyond me though...

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 On Fri, Jul 16, 2010 at 4:31 PM, Sampsa Laine <sampsa at mac.com> wrote: 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...

What are you planning on doing? Sampsa On 16 Jul 2010, at 21:10, Joe Ferraro wrote: 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...

I think I had the 8.50n series... Also, I have taylor up on solaris 10.. just need to configure it...

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). --Marc
