Time for a new release announcement of TCP/IP for RSX-11M-PLUS.
This release contains a lot of fixes and improvements in many areas. I
really encourage people to upgrade, as some of these changes can have a
noticeable impact on performance, and in some cases, stability.
Highlights:
A new name resolver is provided, with better functionality, and better
stability.
A mail daemon is provided, which can handle mail both on TCP/IP, DECnet
and local.
Detailed information on things that have been done since the last release:
TCP:
- Improved handling of TCP FIN packets.
- Improved TCP probe handling, including a bug fix where sequence
numbers in packets could become wrong when probing.
- Improved handling of repeated ACK messages in TCP, which cause
immediate retransmits.
- Added TCP slow start algorithm () had not though I would need this,
but it turned out that under some circumstances, it really helps).
- Added handling of ICMP source quench messages.
- Added ability to set specific timeouts on individual receives from TCP.
- Changed handling in TCP for daemons, so that both queue depth and
actual running copies are checked to adhere to the limits set for
daemons. This makes TCP daemons properly manage potential DOS attacks.
- Bugfixes in TCP. If task activation failed for some reason, resources
were not cleared up properly.
FTP:
- Improved handling in FTP for existing files, which can now be chosen
to be superseded or not.
- Improved FTP MPUT command to not abort on errors.
FTPD:
- Improved FTP daemon Unix-style directory listings.
HTTP:
- Improved error handling in HTTP daemon.
- Improved logging in HTTP daemon.
- Added handling of Accept-field in HTTP requests.
- Added handling of options spanning multiple lines in HTTP.
- Removed binary log file in HTTP daemon.
TELNETD:
- Bugfix in TELNET daemon. Under some circumstances, TELNETD could stop
transmitting data.
NTPDATE:
- Improved handling of no responses in NTP client.
DECnet-over-IP:
- Improved DECnet-over-IP links to get better performance.
IRC:
- Added handling of various text attributes in IRC.
Name resolver:
- New name resolver, with improved functionality, better error handling,
and the ability to abort outstanding requests. Name resolved can now
also resolve other type of queries, such as MX records.
MAILD:
- Added MAILD
Libraries:
- Bugfixes in PDP-11C inet library. Some definitions were wrong.
- Updated quad-time functions with new functionality (affects both
MACRO-11 and all high level languages).
As usual, the distribution is available from:
ftp://mim.update.uu.se/bqtcp.dsk
ftp://mim.update.uu.se/bqtcp.tap
ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk
The documentation is also available through ftp on Mim, or also at
http://mim.update.uu.se/tcpipdoc
The firewall for Mim have now been removed, so no need for the alternate
ports, but Mim is still listening to the alternate ports as well.
ftp: 10021
telnet: 10023

Most of you have heard of the Large Scale Systems Museum, a public
museum in the Pittsburgh area that is focused on minicomputers,
mainframes, and supercomputers. LSSM has been closed for renovations
and expansion for the past several months; we've added nearly a
thousand square feet of new exhibit space and many new exhibits.
On May 6th, there will be a large block party (actually, several
blocks) here in town, called "New Kensington Better Block", with
street vendors and other standard block party fare. LSSM will be
participating in that event with our post-renovation reopening; we
will be open to the public all day with docents on duty. Many of our
systems will be running and demonstrated throughout the day.
In even bigger news, LSSM is pleased to announce the opening of a
brand new wing, the Large Scale Integration Museum, or LSIM. As the
name suggests, the LSIM wing is dedicated to computer systems based on
Large Scale Integration CPUs, from the earliest four-bit 4004
processors through the desktop computer revolution of the 1970s and
1980s. Thanks to a partnership with Pennsylvania-based nonprofit
organization Tristate Technology Museum Consortium, and a generous
donation from the private collection of Corey Little and C/PMuseum,
LSIM will add more than one hundred new exhibits in four thousand
square feet of newly-renovated space located in the same building as
the recently-expanded Large Scale Systems Museum.
Everyone is welcome. LSSM is located at 924 4th Avenue, New
Kensington, PA 15068. For more information, directions, or hotel
recommendations, contact the LSSM via email at info at lssmuseum.org or
on Facebook (search for "Large Scale Systems Museum"). You can also
see some photos of our facilities on the Facebook page.
Please feel free to forward this message to anyone whom you think
might be interested.
Thanks,
-Dave McGuire
President/Curator, LSSM

Sorry to bother you kind folks, but do you know how to get hold of the
password for the hobbyvax account on ftp.usa.hp.com ?
Or has it gone away?
It has been a long time since I last used it and failed to keep a local
copy of the isos I needed (C and Basic mainly)
Cheers for any help,
Tony Blews.
I've been rewriting the code that does address rewriting for mail that
passes between MAIL11 and SMTP the last few days, and I think I got it
sorted now. So, if people have tried, and found either funny, or
non-working behavior please try now, and see if thinks look better.
I've also been testing with VMS MAIL, which uses MAIL11 in some more
creative ways, to make sure it gets translated in reasonable ways by my
RSX gateway.
As a warning, the CC field in VMS MAIL might not be totally correctly
handled yet.

Hi,
call me an idiot, but how do I rectify this problem:
MAIL> r

%JBC-E-NOSUCHQUE, no such queue
Press RETURN to continue reading your mail

Thanks for any help.

We?re downsizing. Also, I haven?t powered this stuff on in years so it?s time to pass it along to someone else.
I have a VAXstation 4000/90 and two VAX 4000/500 that need new homes in the Atlanta area.
The only rule is these may not be sold they must be passed on when you are done with them.

Do anyone have BLISS-16 for VAX/VMS?
I'm now going through various bit and pieces of RSX, and I've found a
few places where the BLISS sources have updates that never have entered
into the binary distributions, which I'd like to fix, but I really need
a B16 compiler to do so. I have VMS 7.3 on a VAX here, but I haven't
even checked if I might have BLISS or not, but since I'm not very
organized in my VMS software department, I figured I should start by
asking if someone else have it, and a bit more order, before I start
trying to sort out whatever stuff I might have somewhere...

Ersatz-11 V7.3 is finished. CDs have been mailed to users with current
update subscriptions, and the free Demo version may be downloaded from
www.dbit.com/demo.html as usual.
E11 V7.3 has the following new features:
- My favorite one: a BREAKPOINT command which accepts arbitrary boolean
test expressions, compiles them into native x86 code (to reduce the speed
penalty), and incorporates them (until disabled with BREAK/CLEAR) into
the main fetch/decode loop). Examples:
break pc >= 2000 and pc < 3000 and @(r4+4) = 42776
(range of code with specified value in block pointed to by R4)
break ci(pc)&177400 = 104000
(about to fetch an EMT instruction)
break phys(14634520) <> 3044
(location at physical address gets changed from expected value)
Errors at run-time are silent. If a specified test causes a bus timeout,
odd address trap, or division by 0, the test fails. Well OK division by
*constant* 0 gives an error but I just mean nothing damaging happens if
the registers aren't pointing where you thought, etc.
- A few rare antique emulated devices: DC11 SLU. Basically similar to
the DL11 (ignoring the extra CSR bits and programming it like a DL11A
works), but it also has a settable baud rate and modem control which
is different from how it was done on DL11s.
- Also the DM11 single-speed serial mux (not that E11 minds running each
line at a different speed, but the original did). It uses DMA for
transmission but also for reception into an in-core FIFO which the
documentation adorably calls the "tumble table". And yes this is the
origin of the DM11BB modem-control option more commonly used on the DH11.
There's a new command to tell DM11BBs which to attach to (the default is
still the DH11 with the same controller letter).
- Finally, the justifiably forgotten TR79F 1600 BPI tape controller for
TR79 drives (really HP7970Es), which includes the parity track in core
with each byte of tape data taking up a word, so it's a pain to program.
But it had 1600 BPI pretty early. The only driver I can find for the
TR79F is in the "TRDP" version of XXDP, which is on Bitsavers as a scan
of a microfiche of the listing. It can be used to load the ZTRAB0
diagnostic (the only other program I know of for the TR79F), but of
course the test immediately trashes your boot tape. I felt dumb.
- Driver for raw ATA/SATA/ATAPI disks (DOS and stand-alone versions).
- Driver for National Instruments PCI-DIO-96 digital I/O card (DOS and
stand-alone versions). It's a bad fit to emulating the DRV11/DR11C
(ASSIGN OA: DIO96: does work but you'd have to wire up an adapter with
buffering since the drivers are rated at only 2.5 mA) but it's probably
the most common digital I/O board around. Even though it's PCI (not PCIe),
it's still made new (at great expense), but cheap used examples are
everywhere.
- Ability to use a digital I/O card to drive real display and switch
registers. Wiring up a blinky-lights board for your $25 eBay PCI-DIO-96
is a lot easier than making one for current PC busses, even if the
100-pin D-shell plug is a pain (but AMP makes an IDC connector that
brings it out to two 50-pin Bergs)..
- SET HISTOGRAM command enables/disables histogram of PDP-11 opcode usage
(which again is temporarily compiled into the main loop when enabled).
HISTOGRAM command displays the results or saves them to a file.
- EXAMINE/DEPOSIT /BYTE /WORD /LONG /QUAD switches support various data
types besides just words. Finally.
- MOUNT <tape> FILE.TAP /LENGTH:n or /SIZELIMIT:nMB enables emulation of
EOT early warning flag (giving the approximate maximum length of the
tape in feet or megabytes). Not generally needed (who minds an unlimited
tape?), but some diags want to fill a tape with test data all the way
to EOT.
- ASSIGN <TTY or digital I/O device> NULL: /LOOPBACK switch. Does what
you think.
- Experimental POWERFAIL command simulates power failures on command,
or SET POWERFAIL command schedules one at shutdown (with a core dump
to a file). Thank you Oleg Safiullin for the idea! Might need some
changes -- I've never dealt with power failures on a real PDP-11.
- Dramatically improved timer precision in DOS and stand-alone versions.
SET THROTTLE in particular is silky smooth, but this improvement affects
many many things.
- All commands that take a time duration as a parameter will now accept a
decimal point and/or unit suffix. The default units are the same as in
previous versions. So instead of SET THROTTLE DELAY=1 (microseconds),
you can use SET THROTTLE DELAY=1.2 or SET THROTTLE DELAY=1200NS (values
will be rounded if needed). I hadn't realized so many places use time
values -- I might have missed something.
There are also many bug fixes and minor changes, but most importantly:
- WMSG.LOG file that grows and grows (in Windows versions). Sorry about
that! That was supposed to be disabled in the released version. Well
it is now.

I have spent some time recently on updating my program(s) to handle
Tops-10 backup tape images, and I am now at the stage when it seems
to work "good enough", so I decided to release this as a beta test.
http://www.pdc.kth.se/~bygg/tops/back10.tar
The basic things work, it can create (-c), do directory (-t) and
extract files (-x), and it reads tapes with large blocks, like the
TSU tapes.
This is very much a work-in-progress, so things might change. If
you have any opinion on how things should work, please let me know.
