Well that's odd.  I just tried to talk to three different 7081s from two
different computers via the serial port using Putty and a null-modem cable.

Port set for 9600,8,n,1   7081 dip switches in the OFF position.

Result a deafening silence even after an "OUTPUT,RS232,ON" command typed
blind at the Putty console.

I have buzzed out the serial cable which looks like:


I know this has worked before as I used the serial port for calibration last

Should I be using a straight-through cable?  My memory says no, but ...

I even rolled back Windows 10 Creators Update in case that was the culprit.
