Multiport serial cables (Fan-out cables)

When a serial interface card provides more than two serial ports there are two possible implementations.

Either
1. The extra connectors are mounted on brackets fitted in empty slots and connected to the card by ribbon cables
or
2. A single connector is mounted on the card and a multi-port cable plugs into this. This multiport cable has many individual cables each with a standard PC serial port connector, either 9 pin or 25 pin.

A multiport cable or fan-out cable may be unique to the manufacturer of the interface card so cables intended for use with different cards but look identical may not be interchangeable. This is my attempt to document those I have discovered so far.
