Need advice for a computer tech......Is there any way to twin two 9 pin rs-232 serial cables together and get them to communicate accurately ? I have tried wiring them in parallel and daisy chaining in series but I can't seem to get them to work. When is parallel I will only get communication from one device. Thx

No, with with 232 in its native form.  you would need a mult idrop adapter or multiplexer.  It is supported with 422/485.  If you are trying to make two devices communicate with each other that is a different story.
