John, You will not need to connect any more pins, but you can try putting a jumper between pins 7 and 8 at the computer end of the cable. No guarantee that it will help, that depends on whether your application tries to do handshaking, but it certainly will not hurt anything.
You did not state that you closed and restarted Winlog32 after you changed the com ports. You might even want to try a computer restart. 73, Don W3FPR On 10/15/2012 5:07 PM, john petters wrote: > Hi Dick, > Just connected the USB adaptor to the serial lead on com 8, where it is, > and opened Winlog32 OK with full control. > Disconnected USB and plugged the serial lead into Com 1 and re-set the > programme to Com 1 and it will display the the frequency as I spin the > VFO, but I cannot control the K3 with the computer.
