Howdy...

I'm looking for a network broadcast message tool for Openwindows 2 or 3.

This tool would allow a broadcaster to send a message to all workstations
running OpenWindows on the network.  Open a window on top of all other 
windows, display the message and require the user to click on an "Okay"
button or the like before the message disappears.

This would allow a sys admin to send out urgent messages to the user who
might not pay attention to their console window or have it covered up by
another tool.

I've been considering writing such a tool, but I thought I'd check and see
if one is available already (not wanting to recreate the mousetrap and all
of that).  If anyone has any hints or suggestions to something like I've
described, please let me know.

Thanks...

There are a number of 3rd parties that offer SIO ports on SBus. In particular
you will find several suppliers that have more than 8 ports/SBus slot. One
that comes to mind is Artacon in San Diego. They offer 16 ports.
I believe GPU also offers hardware that supports large numbers of RS-232
SIO ports.

For SCSA based sun machines (sun4c, sun4m, {sun3,sun4 if you have the
consult SCSA tape}, the SCSA functions scsi_abort and scsi_reset
are probably what you want. The usage of these functions is documented
in the SCSA guide (part number mumble mumble).

To reset a specific target, you have to either have or cons
up the appropriate SCSI address structure. Ask me for details
if you *really* want to know.

But your question is "How do I reset a specific SCSI target". This
could mean that you don't want to know how to do it on a Sun, but
just in general. Hard to say.
 
The basic gist of how it operates is that you select the target
long enough to send it an IDENTIFY message, and then instead of
deasserting ATN* after sending the IDENTIFY message, you leave ATN*
asserted (very host adapter specific). The target may choose to
then accept another message, which in this case can be BUS DEVICE
RESET or ABORT OPERATION (as you desire). Note that a target 
may either choose to not go to MESSAGE OUT phase (which is legal),
or may do something stupid like drop BSY* (drop the bus- the Emulex
MT-02 does this if you leave ATN* asserted after sending the
initial IDENTIFY message. You're at the mercy of passive agressive
firmware writers here). Again, very host adapter dependent here.
You can imagine (my, other host adapter writer's) consternation
when you have to deal with a target that ignores your desire
to send it an important message. Suppose the target accepts the
IDENTIFY message and then goes into COMMAND phase? What command
were you going to send it? I mean, you were just trying to select
the device long enough to abort a current command or reset the
device. Sigh... 

You can always* reset a specific target by resetting the entire bus.
It's too bad that the shotgun pellets from doing this killed off
all other non-specific targets. Tsk.

-matt

*Well, if you have targets that implement the "soft reset" option to
SCSI, it means that they can ignore the RST* line. I dunno if anyone
actually has such a critter (wait, i think there is an IBM 3480
cartridge that does this...)

This is easy to implement even with older shoeboxes. One only needs to

the e.g. MD21 controller. Then one can select the ID just by 'wheeling'
and not jumpering. I have not looked inside an external Sun drive

Pure speculation on my part here, but (a) modem speeds will increase
such that 115kb will eventually be obsolete, so "yes" I would like a product
now that does it; and (b) eventually (I hope) serial will be replaced with
something better (faster, more standardized, just as cheap/easy/available,

so again "yes" I'd like such a board now.  Also given that just getting 38kb
in a serial board for a unix box seems less than a given, I'd like to see
the pressure applied so that high speed connections are made easier to
obtain.

Does anyone have any experience with the PTI PT-SBS540 SBUS card

I currently need additional serial ports, and the 3 on this board
would be enough. (I WOULD like to see an interface speed greater
than 38400,- but would settle for that if necessary).  

AND, since all of my SCSI addresses are currently in use, the
addition of a 2nd SCSI port would either 
	(a) keep me out of trouble in the future
    or  (b) allow me to split the load between the two now.

STILL, I have tried twice to get a spec sheet on this item

Its 6 weeks later and I have yet to see anything...  Not a promising

Organization: CIS Dept, Univ of Linkoping, Sweden
Date: Thu, 20 Aug 1992 22:05:40 GMT

I'm thinking of installing a third ethernet interface in our Sun 4/380
(it has "le0" on the CPU card, and "ie1" on a VME-bus card right now).

My idea was to install another "ie" (One of the old Intel Multibus
ethernet interfaces, with a Multibus->VMEbus card) in it.

Since the config file as shipped doesn't seem to support more than two
ethernet interfaces, I've modified it to look like this:

#
# Support for the on-board LANCE Ethernet chip (Am7990) on many machines.
#
device		le0 at obio ? csr 0xf9000000 priority 3
#
# Support for a second Intel Ethernet interface, using a Multibus
# Ethernet board with a Multibus-to-VME adapter.
#
device		ie1 at vme24d16 ? csr 0xe88000 priority 3 vector ieintr 0x75
#
# Support added for a third Intel Ethernet interface, using a Multibus
# Ethernet board with a Multibus-to-VME adapter.
#
# Added by Peter Eriksson <pen@lysator.liu.se>
#
device	  ie2 at vme24d16 ? csr 0xe8c000 flags 2 priority 3 vector ieintr 0x76
#

I took the "ie2" line from our Sun2 config file and modified it slightly.

Do anyone know if this works or not? Are there any gotchas one should be
aware of?

We have the card that Mike is describing on a SparcStation-2.
However, we seam to have some problems with it.  We use the
loadable device driver that came with the card (STC).
We use the serial lines for dial-in modems.

The problem is that sometimes when people logout they leave a
process hanging on the port in the state <exiting>.
From then on, the only thing that we found to bring that port
back to life is to reboot the machine.

The problem is very elusive, as we couldn't make it happen on
purpose.  It only happens sometimes and not necessaraly to the
same people.


If you know of a solution to this problem we would be happy to
hear about it.

They are used.  If I am not mistaken, your average SCSI <--> ESDI, or
