Subject: Re: problem with "pr_load"
Reference: v6n22
The mistake you made is that you did not allocate the map vectors in the
colormap before calling pr_load(). The Sun Pixrect Manual says (on page
46, under "Read Colormap from Raster File") that "the caller is
responsible for looking at the raster file header and setting up an
appropriate colormap struct before calling this routine." Although you
are not calling this routine directly, pr_load() is. You simply need to do
colormap.map[0] = (unsigned char *) malloc(256);
colormap.map[1] = (unsigned char *) malloc(256);
colormap.map[2] = (unsigned char *) malloc(256);
This makes space for the colormap entries read in by pr_load(). You
should also set colormap.type to RMT_EQUAL_RBG, and colormap.length to
256. Note that the colormap length is dependent upon the image depth, and
is really (1 << depth).

Subject: Hardware flow control
All MTI lines have this, there's no problem.
If the port is a CPU serial port, SUN UK consulting services have a
"product" which provides CTS control of o/p ... so you could ask your
local tech-support in case they have it too!

Subject: Problems with Sun FPA hardware
This is a request for assistance.
The FPA in our Sun-3/160 has stopped working. When we boot the system, it
calls /usr/etc/fpa/fpa_download as part of /etc/rc.local, which decides
that there is a hardware problem and leaves the FPA offline.
We can't find anything on /usr/etc/fpa/fpa_download in Sun's documen-
tation. It produces the following messages in /usr/adm/messages:
(initially)
fparamtest: pipe is hung
FPA RAM test fails, FPA is shutdown!
(the last time we booted after a power down)
fparamtest: nonstable after delay 300 us.
FPA RAM test fails, FPA is shutdown!
The message seems to indicate that there is a faulty RAM chip on the FPA
board. We'd like to try to replace it, if we could figure out where it is!
Does anybody out there have any documentation or knowledge that would help
us make more sense out of these error messages and/or track down the
possible faulty components?.
Since we do quite a bit of number-crunching, we would really like to fix
this, preferably without paying Sun $900 for a $50 fix (we just got a
surprise budget cut).
Prize for assistance in solving this puzzle is our undying gratitude (you
know what that's worth).

Subject: Problems rewinding a cartridge tape on a SUN-3
On a SUN-3, of virtually any flavor seemingly, the rewind of a
tape-cartridge causes the entire system to screech to a halt.
Is SUN planning on fixing this? Is it fixed in the SUN-4? How could they
let a bug like this creep out to literally everyone?

Subject: Mysterious Ethernet problems
We are running release 3.4.2 on a SUN-3/180 server and we are experiencing
a strange problem. First, we get on the console something that looks like
this:
ie0: WARNING: if_snd full
ie0: Ethernet jammed
ie0: lost interrupt: resetting
ie0: lost interrupt: resetting
ie0: lost interrupt: resetting
...
and thereafter, each packet that the server attempts to transmit causes
the last message to repeat, and nothing goes off the wire. Packets do get
received in small ammounts, but nothing is transmitted.
I have considered this problem to be hardware related at first, but the
problem appeared on both our servers at different times. I even got this
problem to repeat itself by using "spray -i" between the two servers on a
loaded net, and got BOTH or them stuck as described above.
The only cure seems to be to reboot the system that is stuck, while part
of the net is disconnected, and then reconnect it back again. If I try to
reboot with all network connected, the problem tends to repeat itself.
NOTE: Our Ethernet consists of one think segment (short) 3 thinwire
segmennts, one ISOLan concentrator (DELNI like) and one ISOLan Multi Port
repeater.

Subject: Need advice on a SUN Configuration
We are looking at breaking the ice and getting our first SUN network. For
starters we are considering buying 6-3/50's 2-3/60's and a 3/280 (as a
file server). Looking at prices and discounts it appears that the 3/280
could be replaced by a 4/280 for just a little bit more $$. The question
is: are we asking for trouble by mixing the SUN3's with the SUN4 server?
Could someone, PLEASE, with experience in running this kind of environment
give some advice? We are surely aware of the power of the SUN4 as a ten
MIP machine, but how much of that power translates into its function as a
file sever? How much the code duplication will eat into our disk storage
(we are getting 900MB)? I read some reports that in a "mixed" (SUN3/4)
netowrk, there are some "I/O retries" on the net due to the SUN3 not
keeping up with the SUN4. Is this true? How easy/difficult is to port C
code written for SUN3 to SUN4? Any other helpful hints you could give us
would be greatly appreciated. Please forward mail directly to

Subject: Need TCP / UDP utility sources
Have a project underway developing SYS1131, with AT&T / Motorola's 5.2 /

The common suppliers of 6U VME Bus cards for 5.x UNIX do not provide
handlers for but a very minimum few sockets. Anxious for pointers to
source for TCP and UDP utility socket code. Thank you ...

Subject: Adding a cgtwo to a 3/75M?
We have several 3/160C file servers on campus that we now want to convert
to essentially 3/180s by taking out the cgtwo and hanging the color
monitor off other Sun 3s. The keyboard and mouse will be replaced by a
terminal hanging off ttya as the console.
What I want to know is if it is possible to plug a cgtwo into the spare
slot in a 3/75M. I spoke briefly with Sun hardware support about this and
they said that the power requirements for the cgtwo might not allow it.
Also I have an older 3/160 hardware installation manual dated Oct 1985
that contains some vital switch and jumper settings that are not
documented in the newer documentation (or so I've been told). There is a
table on page 52 that explains settings for the cgtwo. It mentions
jumpers J100, J200, and J1700. Where are these located on the board? The
board that I have does not have any jumpers labeled at all.

Subject: Third party keyboards?
We have a bunch of Sun-3's (110s, 140s, and 60s). The keyboards are
wearing out at an alarming rate; keys stick, the space bar breaks, etc...
Does anyone know if there is a 3rd party vendor who makes compatible
keyboards?

Subject: HPTermtool?
Has anyone out there seen or heard of a program that that creates a
Sunview window and emulates an HP terminal in the window? I have heard
that Sun has used HP minis in the past for their MIS stuff, perhaps
someone out there hacked up a terminal emulation?
Since this is probably not of general interest, please reply by mail and I
will summarize if responses warrent it.
Thanks in advance,

Subject: Experience with Tektronix 4693D, Parallax Graphics Proc?
Does anyone have experience (directly or indirectly) concerning
* the thermal transfer color printer Tektronix 4693D
(claimed at a full 16.7 million colors);
* the Parallax Graphics Processor Series 1280, which allows
display of a live video image in a workstation window.
More particularily, these two devices can be hooked-up to a Sun. Has
anyone tried it? Thanks in advance for any reply!!
