We have about a hundred engine stands controlled by qnx boxes, with a 10"
ethernet cable connected toWindows boxes. On a serial port this would be
called a null modem cable.
All data into and out of each box is done via sockets. The problem is that
when something goes wrong, there is no way to attach the remote debugger,
save going out to the lab and hooking up a temporary ethernet switch.
My question is, is it possible to create a debug pipe through the Windows
box, such that it simply echoes the byte stream that it receives in both
directions? I would have the Windows box listen on port 8000, and then
connect another socket to qnx on port 8000 upon accept(). This way I would
tell Momentix that it is to debug the Windows box, but it would actually be
debugging the qnx box through this pipe.
