Subject: Re: Sun & VAX/VMS Decnet mail communication
In case this is helpful, we have both Suns and VAX/VMS machines, and we
have Sun's Decnet support ("Sunlink DNI"). The first release is better
than nothing, but is a crummy package. It doesn't support mail
communication to/from VMS, and it doesn't support Decserver access. All
it supports is remote login and file copying, and at least the former is
very buggy; for example, when the Sun is the host and one is
remote-logged-in to the VMS machine, VMS history substitution editing does
not work.
We've looked into ways for these machines to communicate, but it doesn't
appear that there's anything better at the moment. (For mail, of course,
if both machines know how to talk to BITNET....)

Subject: Re: Menu items with varying heights under SunTools
Well, it seems that I was wrong. You cannot create a menu with items that
are of differing heights. The window system creates a menu whose items
are all the height of the largest item. Sorry for the misinformation.
This would be a nice (and orthogonal) feature in the menu library. How
about it, Sun?
Sigh...

Subject: Re: Problem connecting a Hayes Modem
I know what your problem is, but unfortunately, as far as fixing it, you
may be in trouble. The problem is one of two things. The first is that
you do not have the modem configured for short numeric responses. Since
the debug info has "OK" in it, it is clear that you are not sending the
numeric codes. However, that may be just the begining of the problem.
The second potential problem is too much hard-coded trash. Specifically,
your modem will send CR,LF,"0",CR,LF (i.e. 5 characters) when tip and
uucico expect "0",CR (2 characters) . Most Hayes compatible modems just
send the return code and a CR, but some send CRLF code CRLF. This makes
everything print pretty on the terminal. But it breaks tip and uucico.
In fact, tip and uucico scan for the CR and assume that it represents the
end of line, so they thenm throw out everything else as trash. The only
way to fix it is to change the source and recompile. There may be a
workaround, but you would not be able to use hayes mode with tip and
uucico.
These things should be in some kind of configuration file. Why aren't they?

Works great! And you can even give "-l" arguments to it. But you have to
be running suntools to use it!
Looks great, too. I have a question or two with associated nits to pick:
1) Is the csh required for this? It doesn't seem to use any csh features,
but perhaps it is necessary to get job control/signals/process groups
right. Otherwise, you might want to use /bin/sh. Can you elaborate on this?
[[ Habit. Whenever I start a shell script I always type "#!/bin/csh -f"
as the first line. --wnl ]]
2) If you *are* going to use csh, use its features! Get rid of the
basename call (set h=$0), and replace `$h' with `$h:t' in the last line.
Note that colon suffixes do not work on $0, $1, ... arguments.
[[ Absolutely correct. Those who use this script might want to make the
mentioned changes. --wnl ]]
3) Perhaps you might want to use the `hello world' icon instead?

This gets a bit booring after a while. It also fills up the root file

Subject: `pc' ignores program
The following demonstrates what I consider a bug in `pc'.
Script started on Thu Apr 14 15:52:02 1988
iesd% ls
test1.p test2.p typescript
iesd% cat test1.p
program test (input, output);
begin
writeln ('Hello, World');
end.
There is an error in pc.
* iesd% pc test1.p
* iesd% ls
* test1.p test2.p typescript
iesd% cat test2.p
program test (input, output);
begin
writeln ('Hello, World');
end.
{There is an error in pc.}
iesd% pc test2.p
iesd% ls
a.out* test1.p test2.p typescript
iesd% a.out
Hello, World
iesd%
script done on Thu Apr 14 15:52:58 1988
On the lines marked with *, note that pc did not generate a binary,
neither did it generate an error message. If I put a quote in the text
after "end.", I get an "Unmatched ' ..." error. This shows that the text
is parsed.
Now, I don't care if some random text after the end of a program is
considered an error or is simply ignored. But the current behaviour is
*not* OK. (Consider when this happens in one file out of many, compiled
and linked by Make. You have a bug, so you change the program. No use. You
put in some print statements. Nothing is printed. Very funny :-).
This is on Sun 3/X's running SunOS 3.4 and 3.5. On a Vax, running Ultrix
V2.2, pc compiles without bothering about text after "end."
I have CC'd to sunbugs.

An important change between DNA4.0 and DNI5.0 is that in 5.0 the dnalogind
process is initiated by dnaserver. This means that in your /etc/rc file
you should start up dnaserver:
/usr/sunlink/dnaserver & >/dev/console
(In 4.0 you would have started dnalogind there. If you do this under 5.0,
dnalogind dies after the first session is terminated.)
You also have to put in the dna account in your /etc/passwd file. As the
DNI System Administrator Guide says (sect 4.3) "If the system
administrator chooses not to define the default dna account, remote login
to the Sun node will be possible only if the system administrator starts
dnalogind manually each time someone wants to log in."

Subject: Format for byte encoded rasterfiles?
Did anyone know the format of Suns runlength encoding in the Run
rasterfiles. I also appreciate a RTFM if you enclose the manual name and
page number. The only information I have found is this short comment in
the "rasterfile.h".
#define RT_BYTE_ENCODED 2 /* Run-length compression of bytes */
Please note, I am asking for the format not how to read a rasterfile with
the sunlibraries.
All hints is very much appreciated.

Does anyone know of a postscript driver that will format output to a dot

since we hooked a LaserWriter to the system. However 95% of what is
printed never leave our lab, so hi resolution is not always needed. Any
Ideas?

Subject: Looking for information about terminal servers
I am looking for information concerning ethernet terminal servers or any
similar equipment. Any help will be greatly appreciated. If I missed a
recent posting about this sort of thing, please tell me who to contact for
the information.
We would like to be able to connect a number of terminals to the ethernet
and allow users to log in to our vaxes, suns, etc. It would also be VERY
handy if we could use them for uucp or SLIP on systems without ethernets.
ANY other suggestions for connecting terminals and computers which
otherwise have no network connection would be appreciated.
Assuming that it is possible to run uucp through one of these to an
arbitrary system on the net, does (or would) its performance drop
miserably for normal terminal sessions? How many uucp sessions do you
think it could handle?
Thanks in advance for any comments. If I get lots of info (and anyone
else cares) I will summarize to the net.
