I need a longish serial cable to get from the workshop computer to the
bench. Say 4 mtr. I already have the D connectors and wonder what
would be the most suitable cable I have 'in stock' Only need the send
and return - no 5v. Would balanced mic cable do - or two co-ax? I do
have some decent video co-ax but two would be a bit big to fit the D
connector shells.

4m is not long for an RS232 style serial cable run, and almost
anything will do, although it gets more critical at higher bit rates.

The device I need to connect to says 115200 baud.

Conventionally, untwisted screened cable is used, although there
are variants which use balanced drivers for the signals, which
require a twisted pair per signal.

This is definitely unbalanced.

Not sure what you mean by "return". Do you mean send and receive, or
just unidirectional send and the ground return wire?

No - TX and RX and obviously ground. Those are the only connections on the
device DB9.
