I need a longish serial cable to get from the workshop computer to the

be the most suitable cable I have 'in stock' Only need the send and
return - no 5v.

RS232 serial is +/- 12v. USB is 5v... But you refer to D type
connectors so I assume you mean RS232. B-)

A bit of twin screened mib cable will work. Serial cables are
normally only x wires with an overall screen. No twisted pairs or
anything the signals are not balanced and quite big.
