[mod.computers.vax] TCP RESPONSES, COMPRESS, AND DLVJ1'S

SYSRUTH@UTORPHYS.BITNET.UUCP (02/10/87)

OK, here we go one more time. This is the third time I have tried to post
this message (an URGENT one) to the list. I have not seen it come back. What
I HAVE seen is about a dozen messages along the lines of "mail undeliverable
for 2 days; will try 1 more day" etc. Some of you also appear to have
exceeded your diskquota and it is undeliverable for that reason.
 
My apologies (again) if you have seen this before. But I desperately need
an answer to point 3, and I have received neither the message back, nor
any replies. It is not a problem with my machine; MAIL waits for it if it
is down (and then comes through in a torrent!). Does anyone have any idea
what might have been happening? Is "info-vax@sri-kl.arpa" still the right
destination, or did I miss that, too? Is there a BITNET address I could
send it to instead (anybody out there have a 99% reliable gateway to
sri-kl, or are you all going through Wiscarpa?). No offence to the Wiscarpa
people, but this is getting very hard to take. Usually I see my own message
within 24 hours of sending it!
 
Anyway, here it is...

To:     Orig_To! info-vax@sri-kl.arpa, SYSRUTH
Subj:   tcp info file, MAIL COMPRESS, and DLVJ1's
 
Several things this time:
 
1. I could not reach the following people who requested a copy of my collection
   of TCP responses: R. Haslam, I. Ahn, D. Morgan, and S. Cavrak. Please send
   me a FULL address (some of it gets truncated or left out in the messages you
   send me) if you still want a copy. Preferably something not too far
   removed from BITNET if possible.
 
2. A note about the MAIL COMPRESS command - it does NOT lock the MAIL.MAI file,
   or at least it didn't in 4.3. I got a message once during a COMPRESS and
   had to use the SET FILE command to get at it - it was in MAIL.OLD. Maybe
   they have fixed this in 4.4 (did they FIX anything in 4.4?). I would be
   interested to know what sort of message it gives someone trying to send
   a COMPRESSor mail. "File locked by another user" would not be very helpful.
 
3. A plea for HELP! We have just received a DLVJ1-M 4-line asynch. terminal
   line Q-bus interface. It is covered in jumpers. According to the technical
   manual that came with it, some of the features (speed etc.) are software
   settable. It is my understanding that this device uses the DLDRIVER. Is
   this the case? Is it truly software settable or do we have to pick a
   speed, wire it, and stick to it? What device names do things show up as?
   Would the SET TERM commands work the way they do with DZQ lines, or would
   we be stuck with SET DEVICE?
 
   I would try some of these things out for myself, but it is a production
   machine being used exclusively by one group in our department, and I
   can't take it away from them for long to play with it. CSR's and vector's
   (ignore the last apostrophe) should not be a problem as the CSR is uniqie
   uniqUe (having problems today - got bitten by a squirrel this morning)
   and we have nothing else at vector 300. Which brings me to another
   question - since the driver comes with uVMS, will the device autoconfigure?
 
   Thanks for any help you folks can give on this one. I have no exposure to
   the original UNIBUS device this is based on, either, so you'll need to
   get down to reasonably basic points (this is what I get for being non-
   technical - but that's changing!).

DLVJ1's.....what I remember from a quick (disgusting) look at one:

1. They are not silo'd or DMA capable so you should have them up at
the front of the backplane...

2. Some functions are software selectable, others are put in by hard
jumpers.... it depends on the operating system (some have support for
the software selectable features, others do not).

3. According to my Microvax hardware manual, microvms does NOT support
the DLVJ1 yet.....in 1985.... and my newer 1986 manual doesn't even 
mention it.....

4. DLVJ1's are really 4 dlv11's on one board so you must consider it as
4 seperate devices with four seperate csr's and vectors not just the 
one at 300.

5. Since 1 above and other internal considerations, DL's are NOT ABLE
TO RUN AT OVER 1200 BAUD RELIABLY!!!!!!!. If you do so, you will every
so often lose the rx or tx interrupt enable and that channel will be
useless until totally reset (on vms i think it requires a reboot, on
rsx you can poke the csr through the I/O page from dcl....)

6.  If you really need to know whether microvms supports the dlvj's
let me know direct and I will peruse the 'fiche...
