ctrl-c aborts IDL on sun? [message #38322]

I'm used to using IDL on an alpha but recently forced to use a sun.
I discover that aborting a script with ctrl-c tends to kill IDL:

19 wmc@bsucena>% Interrupt encountered.
% Interrupted at: WREADU 35 /users/icd/wmc/wave/pros/wreadu.pro
% Unable to read/modify terminal characteristics.
I/O error
wmc>

Does anyone know what this means? google doesn't. If its relevant, wreadu is
in the middle of doing unformatted i/o.

tcsh. Now its shell-ish not IDL, I've asked our own helpdesk and have
soe hope of an answer.

Maybe it is command shell specific and should you look in the shell man
pages. What shells are you using?

Hmm, now I have to confess, it may be my start up script...

If I just say "idl", it is robust. Ditto "nice idl $WU_LIB/START".

BUt when I put "nice idl $WU_LIB/START" into a script and run the
script, it becomes ctrl-c sensitive. How odd. But probably not
idl's fault.

Hmm. Thats not too optimistic-sounding.

n fact, simply typing ctrl-c at the command prompt when nothing else
is happening is enough.

This doesn't generate any odd err messages, just gets me out of idl.
Worse, it doesn't kill the idl process - that goes mad somewhere and
eats the cpu. But fg doesn't work.

Hmm, yes, I was rather hoping for a solution, not a hint that the
problem may be rather less soluble than I feared :-(

This is probably of minimal use to you, but I see something
similiar when attempting to run IDL 6.0 in 64-bit mode
on a Sun SunBlade 150. IDL will start up, but as soon as
you try to do just about anything, you get an error
message and IDL hangs, e.g.
IDL> window, 0
% Unable to read/modify terminal characteristics.
Bad file number

The 32-bit version works fine on this system, and both the 32-
and 64-bit versions work fine on a Sun Ultra.

RSI tech support was unable to make any progress on this problem :-(

I have a SunBlade 1000 and ^C does not dump me out of idl

IDL> $cat /etc/motd
Sun Microsystems Inc. SunOS 5.8 Generic February 2000

IDL> print,!version
{ sparc sunos unix Solaris 6.0 Jun 27 2003 64 64}
IDL>; hit ^C here
% Interrupt encountered.
IDL>

In other words, it works as I would expect it to work. So, it is not a
universal problem on SunBlades.

Thanks for the thought. I've just re-written my startup script
in bash and the problem has gone! Hurrah.

No worries. I am just sorry you had to downgrade. Solaris is fine and I
have been quite happy with the hardware overall, but uSparc CPU's leave a
bit to be desired.

I agree with Pepijn that it is probably related to your shell. FWIW I use
bash and haven't run into any problems.

I did try another shell... somewhere on this thread. With bash its fine.

But thanks for your onintr - that fixes the problem too, and more
cleanly.

And I have a SunBlade 1500, not having any problem. I do remember
having a similar problem (although without the IDL session running
amok & eating CPU), and that problem was fixed by something related
to the "onintr" command.... see "man onintr", and also try IDL under
a different shell.
