OK, you had a connector to which you could directly connect a terminal with a straight-through cable, which is equivalent to a "normal" COM port (male DTE) plus a null modem. What's "wrong" is that this makes the port DCE, which should have a female connector. (To put this another way, when flipping the pins (DCE vs DTE), you should also change the sex of the connector.) > What we > did was make our own modem adapters so that the signals would be "straight > through", and it worked fine as I said. Sure; you changed it back to DTE. But what you ended up with was a null modem cable with opposite sex ends. -- John Owens SMART HOUSE Limited Partnership john@jetson.UUCP (old uucp) uunet!jetson!john +1 301 249 6000 (internet) john%jetson.uucp@uunet.uu.net
