On brightening up a picture looking into the ports, I see you're right about
where the connector key is. Looking on Google, I found that other people cut
the key off normal RJ12 connectors in order to use them with RJ12 DEC MMJ
sockets: http://www.tldp.org/HOWTO/Text-Terminal-HOWTO-11.html#rj_conn
I also found that unkeyed RJ12 plugs are available:
http://www.cxtec.com/products/item_detail.php?mfg_id=66&manufacturer_part=5-555042-3
. Looks like this might be the way for us to go when making up our own leads.
We'll have to watch the pin-outs though, and whether just one pair of wires is
reversed in the protocol etc...
Looking at a PDF of these plugs, it seems that there's a standard key shape that
could theoretically be moved to any position sideways. Also, I found at least
one site where people make rubber surrounds for these connectors - perhaps
someone else makes custom plugs too?
