My VAXstation 3100/m30 has these crashes since about half a year. I
opened it up and dug around the inside at this time so I thought,
maybe I've broken something.
But recently I've installed 1.5 from CD and there it doesn't crash.

The machine boots into single user mode without problem. I also can
mount paritions r/w and modify files on them.

The crash happens when fsck starts:

# fsck /dev/sd0d
** /dev/rsd0d
panic: lockmgr: no context
syncing disks... Trap: type 2, code 0, pc 80000717, psl 4140000

     How does netbooting look on that version?

DECServer 300, revisited

Hi,

I just got a DECServer 300 as a present (yay!), and I'd like to set it up
as a console server for a number of NetBSD machines. I've read what
threads I've found in the port-vax mailing list archives, but while there'
is discussion about using it in general, there are very few actual
examples of use.

So I'd like to know if someone out there might give me a really quick
HOW-TO on using this. I gather that based on what I've read, I will use
this with standard telnet rather than worrying about LAT.

Do I need SH1601ENG.SYS, or is that just if I want to use the latest
firmware?

Is there a manual on the Internet?

What if I don't know / have the original passwords? I haven't even plugged
it in yet...

Finally, is there a definitive answer on how to tell the DECServer 300 to
send a break to the serial console?

Thanks!
John Klos

I think the 700 has firmware the 100,200, and 300 must
be loaded from mop every power up.

It will cause a framing error; it will not necessarily produce a break
condition, and if it does, it's likely to produce _two_ breaks; ideally
you should use a NUL (^ <at> , character 0x00) instead - that will produce
only one long spacing pulse, not two.  I'm not certain how a break is
defined - most devices' output break condition lasts something like 250
to 300 ms; at 110 baud, even a NUL produces only about 82ms of spacing
(nine bit times: the start bit and eight data bits).  If you can set
the baudrate as low as 36 baud, that will give you 250ms from a NUL; 30
baud, 300ms.

Of course, it's quite possible that the device you're talking to will
be perfectly happy with any framing error.  But don't count on it until
you've tried it; not all devices act the same on breaks as on other
framing errors - for example, the 8530 chip (used for the serial lines
on older Suns) has separate bits, one for breaks and oen for framing
errors (I don't know whether all framing errors or non-break framing
errors), so whatever's driving it can tell the difference.

Re: DECServer 300, revisited


While we're talking about DECservers..

I'm using a 90M for console access - there are telnet 
port listeners defined for direct access to each port 
(security isn't a concern right now).

It works just fine, except for one thing: staircasing,
and the odd dropped character after power cycling the 
device attached to the port.

Disconnecting and reconnecting the telnet session fixes 
the problem, but it's annoying to have to.

Any idea why it does this?

regards
jeff

I don't think the 300 supported telnet just some of
the emulex clones at that time now the 700 ...

Will have to do some looking because I'am not sure.
