I'm trying to use GDB from NT and do remote debugging for m68k over
the serial line.
I have had problems with B19 to interrupt (Control-C) after a
"continue" command on the GDB. It looks like GDB doesn't get the
signal while it is waiting on the serial read(blocked).
I upgraded my Cygwin to B20.1 tried compiling GDB and using it with
It helped to some extent and GDB is able to catch the signal
SIGINT while the serial read is blocked and while GDB is waiting for
something to come on the serial line. But, this works only one time.
GDB cannot get this signal anymore in the same shell session. Starting
a new GDB session in a new shell helps.
Also, I downloaded the Jan 15th Snapshot and installed the
Cygwin-inst*. The problem with this version is that the GDB doesn't
get the signal at all while waiting for the serial read. It behaves
the same as Cygwin B19 behaved.
I think the problem is in the handling of signals while doing the
blocked I/O calls.
Any help or suggestions will be appreciated.
