As you feel that strong about it I googled to have some backup for what I assumed to be true, and came across this page: http://digital.ni.com/public.nsf/allkb/1EE0DD8AF67922FA86256F720071DECF It shows that the so-called "null-modem" cable is to connect a two devices of the _same type_ together (in other words: crossing the TXD and RXD wires), and the "straight thru" to connect a DCE to a DTE. To be honest, I have allways though of a "null modem" cable as being the one with just TXD and RXD (and ground ofcourse) connected to the other machine (regardless of if it was of the same, or opposite type), with the control lines connected back to their counterparts on the same connector. So, it looks like we both made a mistake. :-) > P.S. I've been using null modems for >50 years ;} I have been using them, and others of its kind for quite a while too, and have even been known to solder a few myself. Regardless our time that we used them, we both seem to have misremembered. Also, age has little meaning on the "interwebz". Knowledge is the only thing that counts here. :-) Regards, Rudy Wieser P.s.
