[Yaesu] Straight and Null Modem serial cable

Ed:

Note that the Yaesu FT-847 uses a simplified null modem configuration ie.
pins 2, 3, and ground.  Simply go to Radio Shack and pick up some shielded
2-conductor audio cable and 2 male DB9 serial plugs with hoods. Solder the
two conductors to pins 2 and 3 and the ground to pin 5.  On the other end do
the same except SWITCH pins 2 and 3.  That's it !

Subject: [Yaesu] Straight and Null Modem serial cable

Sorry for the ignorance. Can someone tell me the difference between a
"straight serial cable" and a "null modem" type of serial cable.

Been trying to connect my FT847 to my notebook with no avail. No problem
with my FT 920. The manual says one must use the null modem type. Not sure
if I got the right one.

Software is LOGIC 5.2

Thanks!
