To get around uucp's setting the modem's autoanswer bit, patch the dial
string in /usr/lib/uucp/uucico using adb, GNU emacs, or even textedit (if
you then use something else to delete the newline textedit adds at the
end).
ATV0Q0E0S0=1S2=255S12=255
^
change 1 to 0
You can likewise patch tip. Adding the S0=0 to the phone number in
/etc/remote works fine for tip unless you want to exploit /etc/phones by
putting a "@" in the pn string: the "@" isn't recognized as special if
there is other stuff in the pn string.
On Gould systems running UTX 2.0, you can specify the interaction of tip
and uucp with the modem in /etc/modcap (analogous to termcap). This
supposedly lets you adapt tip and uucp to just about any modem.
Presumably, other systems have something like this too; I wonder why SunOS
doesn't.

> What can you suggest?
1) Patch the uucico binary (I personally do not recommend this, but it
works _very_ well). As long as you copy it first you should be okay.
2) Use the following shell script: (call it uureset or whatever)
#!/bin/sh
# Change baudrate and anything else system dependent
cu -s 1200 S0=0 >/dev/null 2>&1
exit 0
Call it in your /usr/lib/uucp/uucp.* scripts at the very end (so it gets
called after all of the polls) and execute it by hand after each manual
uucp (ie. not started by cron via uucp.* scripts).
I have better work-arounds for TrailBlazers... to get auto-answer to turn
on and off via modem control signals. Tricky, but it seems to work. TB's
are more difficult since they are nice about resetting to default/EEPROM
values when DTR drops. But they also will not answer while DTR is dropped
and therein lies the trick. Also, since TBs do not have an Auto-Answer
indicator, this method gives visual feedback to the answer status---
necessary for my home machine on my normal telephone line!

Didn't you have to specify the dialing sequence in /usr/lib/uucp/L.sys?
You can do the same thing there that you did with tip; reprogram your
modem.

Subject: Re: netstat -r is broken with sub-netted Class B nets
It is not really netstat that is broken. Use "netstat -n -r" to see what
it really gives you. Netstat uses getnetbyaddr() to convert the net
number (128.118.6.0 in your case) to a name. In turn getnetbyaddr() uses
a routine called nettoa() to truncate the net number strings
("128.118.6.0") at the appropriate "." before looking it up in
/etc/networks or with YP. The nettoa() routine is very dumb. It just
truncates based on the class of the network number. It knows nothing of
subnets. At this level I am not sure what else it could do. Maybe
getnetbyaddr() should have an optional subnet mask argument.
I (almost) always use the "-n" option to netstat because it is much faster
and when things are broken (which is usually the case if I am using
netstat), it does not hang trying to look up names. Also, gateways that
have multiple interfaces but one official name do not show up as
meaningful information. Besides, you should have all you IP addresses
memorized (:-)

Subject: Re: ftp problem
You should check your ifconfigs in /etc/rc.boot to be sure they're really
happening. (Best check: type b -sb at the monitor prompt, then do the
stuff in rc.boot by hand, including the ifconfig.) I've seen (and
reported to Sun) a problem where diskless nodes will seem to work OK if
they learn their IP address purely via reverse ARP, but the address in the
ifnet structure has garbage where it should have zeroes, and binding local
addresses fails when that garbage gets compared to zeroes somewhere else.
The ifconfig stuffs the address into the interface structure properly. I
suspect that this problem is in all SunOSes up to (but possibly not
including) 4.0.
I'll also bet that the ifconfig is failing on the clients because of some
interaction with YP and the nameserver. You might try putting the client
IP addresses directly into their ifconfig lines in rc.boot and see if that
helps.
(Does it sound like this has happened to me before?)

Yes, we've seen this too. We are running SunOS 4.0 on a Sun 4/280, with
NFS mounts to other Sun 4/280's and Ultrix 2.0 on a VAX 8700. This
happened a lot when we first got the machines and were setting them up.
Now we don't notice this, since things are relatively stable and file
systems only get mounted at boot, and stay that way till we crash or
shutdown. I don't think we ever reported this to Sun, though we probably
should have. I quick look at the "Software Technical Bulletin"s (index in
Sept. 1988 issue) did not reveal anything on this.

Subject: Bitnet mangles source files
While I hadn't run into ^ as a problem for uuencoded files through bitnet
(such nodes needs to be spoken to firmly!) I had run into the
trailing-space-deletion problem on several occasions. Although deleting
trailing spaces is enough to upset uudecode, it is not an
information-losing operation because uuencode produces fixed-length lines
and hence deleted trailing spaces can be reconstructed. So either put
another filter ahead of uudecode to restore trailing spaces, or if you
have the uudecode source hack that up appropriately.
The advantage of this approach is that you don't have to wait for the rest
of the world to change to a new uuencode convention.

Subject: Remote booting a Sun-3/280 -- failure!
We have a new Sun-3/280, and are trying to get it set up. It doesn't have
a local tape, so we are following the procedures in "Installing UNIX on
tapeless workstations". We've been through this before, but haven't
encountered this particular problem before (at least, as far as anyone
still here can remember).
First, a little background. We're on a class-A network (35.xxx), so we
need to boot a little differently than on class-C. The command we used to
start copy was:
>b ie(0,80c65,0)stand/copy <-- 80c65 ==> .8.12.101 (server addr).
This works fine. (BTW, the address of the new machine is 35.8.12.60.) The
problem is that when standalone copy is running, we try:
From: ie(0,80c65,0)minifs
and it doesn't work. Using 'traffic' to check the Ethernet reveals that
the new machine is sending ND requests to the server, but the server isn't
sending anything back.
Suggestions? Any help would be appreciated.

Subject: NFS file inconsistency bug
[This may be a re-hash of a previous discussion, but I haven't seen a
"reproduce by doing this" description yet, so here is one.]
Environment:
Host A - Sun-4/280 server running SunOS 4.0
Host B - Sun-3/60 diskless running SunOS 4.0
Symptom: Filesystem is local to host A and NFS-mounted by host B. A file
in that filesystem appears to have different contents when viewed from
hosts A and B.
Reproduce-by:
1. Run this program on host B.
main(argc, argv)
int argc; char **argv;
{
int fd;
(void) unlink("testfile");
fd = creat("testfile", 0777);
if (fd < 0) {
perror("cannot create testfile");
exit(1);
}
write(fd, "foo\n", 4);
fsync(fd);
close(fd);
}
2. Give this C-shell command on host A:
echo 'foo bar' > testfile
3. Give this command on hosts A and B:
od -c testfile
Compare the output from host A to the output from host B.
We have observed that removing the fsync() call from the C program will
cause the problem to go away.

I am looking for a dvi previewer that will run under suntools. I recently
tried to use dvipage, but we don't have the necessary pxl fonts here, and
apparently no one is willing to make them. Does anyone know where I can
ftp a set of the fonts (at least enough of them to test out the program)?
Even better, does anyone know where I can get a previewer that doesn't use
pxl at all?

Subject: Frame Maker to (di)troff translator?
Chuck Musciano's plug for Frame Maker reminded me of a product enhancement
I requested from Frame Technology. Under the Document.save options I
would like to see a dump to (di)troff format. So I could create
documentation using Maker and display it on a ascii terminal (with the
'man', troff, nroff or other related command). I know I can just dump the
text but that is kind of crude. Unfortunately Frame said that although
they have had several requests of this nature, they have no plans to
implement this in the near future.
>From looking at the Maker Interchange Format (MIF) it does not appear too
difficult to make the translation of text (graphics is another story).
But, before I dive in, has any one else out there considered this? i.e.
done any work in that direction. I would prefur to translate to ditroff
macros but my Sun only has troff and troff doc so that will be my first
choice. Any comments suggestions or the like would be appreciated.
Thanks!

Subject: TTY Windows in Sunview?
First, thanks to those who've helped with the font problem I mentioned
earlier with Sunview (it was mostly my error in mis-reading the docs...).
Next, to a question which I sort-of tried to ask earlier:
On our Sun 3/50, an application which sets up subwindows using a TTY
process in one of these windows will only execute a startup process in
this TTY subwindow ONCE (i.e. I have a program that runs another program
which is forked in this TTY). Is there a hard limitation on the number of
TTY windows in one application ? and Why, when this TTY program is
finished and the TTY window destroyed, can't another TTY window be created
in its place ?
I've experimented with several combinations of subwindows and TTYs, and
have found only ~20 subwindows can be created with 1 TTY, 15 with 2 TTYs,
etc. And if the TTY window is destroyed and then recreated, the number of
subwindows decreases by 2*(#TTY's). Any advise or ways around the earlier
problem ?
Thanks in advance,
Paul J. (pj2f)
