Re: Octave chokes on this in some systems

[Paul Kienzle]

octsync.tcl is in octave-forge/extra/soctcl.

The ctrl-c behaviour is incorrect, but fixing it is a very low
priority.  Normally the function is running detached and needs
to be sent a kill signal.  Fixing it requires interrupting
the accept() call on Ctrl-C which I don't know how to do.
