[R] CTRL-C behaviour with RODBC on Solaris2.8

The ODBC driver manager is unixODBC-2.2.11.

I will continue investigating other causes and am extremely grateful for
the time you took to see if the problem was reproducible on any of your
systems. The lack of reproducibility is valuable information to me.

Thanks very much again for the time you took to investigate and reply.
Thank you very much also to the R project and all the great things it
has done. I wouldn't be here without you!

Best wishes,
Jagat

This is nothing to do with RODBC, and not reproducible on any of my
systems.

Investigate your unstated ODBC driver manager and driver for possible
causes.  Something other than R has uninstalled the signal handler for
SIGINT, and a rogue shared library is the likely cause.

And please learn to give credit where it is due, instead of blame where
it is not.  (RODBC attracts far too many careless attributions of blame,
this being the second just today.  Yet words of thanks are very, very
thin on the ground.)
