[plug] PPP Connection having problems

I've looped-back the RTS and CTS rather than running them through the cable,
because the cable is only 3 wires.

I'll give that a go. I assume I have to add that at each end.

I've been using a lcp ping to hangup at each end, seems to work well, since I don't
have a cable with enough cores.
