Why? DEC-10 is big endian... :-)

Big endian, I use htons() to prepare the length for network

Big-endian, for a DEC-only protocol?! Heresy!

I propose the following format:
+-----+-----+-----+-----+
|11-15|03-00|10-07|04-06|
+-----+-----+-----+-----+
Note the following
1. Each cell is nibble, left most cell is the most significant half of the
byte it represents
2. The cells are the bits numbers of the 16-bit number being represented, 0
is the least significant bit
3. Where the nibble bit range is descending the bits start at the most
significant bit and go to the least significant bit
4. Where the nibble bit range is ascending the bits are in the reverse
order.
Hopefully that is neither big endian or little endian so there won't be any
arguments. I call it middle-endian, or rob-endian for short.
Happy? :-)
Regards
Rob
Kari, that is the correct answer

Set boot defines the boot device, but set halt <value> is the parameter
for restart control.

I've just been donated (by Saku Setala) a pair of MicroVAX 3400s.
One of them is set up as a satellite node and boots fine off ESA0 - however, I can't figure out what I need to do to make it automatically boot when powered on - anyone know what switch / console command I need to give to make this happen?
At the moment it starts up to the >>> prompt and if I type boot, it boots happily. I'm just trying to get it to autoboot instead.
Would it be dep bdr 0 as it is in simh for auto boot on a real VAX?
(if i'm wrong, let me know)

No. It uses a TCP connection. Each buffer received from the device
driver is sent along on the TCP connection with a 2-byte length prefix,
and that is it. So no DDCMP underneath.
OK cool. Little-endian?

If you want to really make your head spin, imagine DMP/DMV emulation
(DDCMP multipoint).
I've never really understood this. Is it a broadcast net, or what?
I'm pretty sure I have a pair of DMVs in this mess somewhere...

It is being merged into the official SIMH builds by Mark Pizzolato, I am
hoping it will be in the next release. I just checked with Mark and he is
not ready to share the code quite yet, but there should be some almost
official code to share soon.

Rob

If you want to peer with me using DMC11 let me know. I will need to
know your IP/DNS address and a port you want to listen on. You can
download a Windows executable of the VAX780 emulation with DMC11
support here:
http://sdrv.ms/Lmg33s I am hoping that the DMC11 will be in the next
release of SIMH, and perhaps in the PDP11 emulation too.
I'd be interested in trying that. The Unibus emulation should just carry
over.
Is the source available?
