What normally happens is that you blow the auxbus, and end up with a dead

there was nothing connected to that pin on your cable.
That sounds like an accident waiting to happen!
Ideally Elecraft wouldn't have used a 9 pin D connector, but, as they
have, I think I may isolate that pin initially, maybe by not installing L1.
Some other thoughts were:
- connectorising the signal on the jumper cable;
- connectorising L1;
- inserting a back to back plug and socket into the D connector
to isolate the non-standards lines.
It sounds like the other risky signal is the 12V one, but I think the
worst that happens is that the filter choke acts as a fuse. It also
isn't at risk with normal RS232C signals, only with the ground
connection. Is it worth trying to add a PCB mounting fuse? Would the
voltage drop be too large?
