   From 30-year-old notes:

The loopback connector part number is: 12-25628-01.  To make one:

Short Transmit data to Receive Data,        o 1
pins 2->4 as shown in the diagram.    7  o +-+  o 2
(view looking at the plug).           6  o | |
                                       5  o +-+  o 3
                                             o 4
