22.3.1. Common Serial Cable Types - PC Hardware in a Nutshell, 3rd Edition [Book]
July 24, 2003 - The term null-modem cable is often misused to mean any cross-over cable, but a null-modem cable is really just one variety of cross-over cable. PC serial ports are usually configured as DTE. Modems, mice, trackballs, digitizers, and scanners are usually DCE devices, and so connect to a PC with a straight-through cable.

The most popular of these is the DE-9, commonly (and incorrectly) referred to as DB9. Either or both of these connectors can be used for a serial cable. There are two general types of RS-232 serial cables: standard straight through cables (wired 1-1, 2-2, 3-3, etc.), and null modem cables.

They are commonly known as "console cables" or Rollover cables. They are NOT Ethernet! They are often flat CAT3, or just 8 conductor ribbon cable. All console cables are null modem cables, it is just the pin out that is sometimes different.

the top cable is a DB15 splitter. Game controllers in the 90’s before USB used DB15.
the second cable is a serial cable. most likely for a router or switch console connection, but i have seen them to connect motherboards to sensors and other equipment in specialized equipment, like inside a treadmill to connect the console.

What are the Differences Between Serial and Parallel Communication?
February 20, 2026 - Serial cables are much more common to spot in everyday life. The USB cable is an example of a serial style cable. As you can see the connector head looks substantially different than the parallel cable simply because it is smaller and does not have visible pins.

August 18, 2021 - Only very few computers have been manufactured where both serial RS232 channels are implemented. Examples of this are the Sun SparcStation 10 and 20 models and the Dec Alpha Multia. Also on a number of Telebit modem models the secondary channel is present. It can be used to query the modem status while the modem is on-line and busy communicating. On personal computers, the smaller DB9 version is more commonly used today. The diagrams show the signals common to both connector types in black.

Yes - I would call that a Null Modem cable.
If the cable you get (or make) doesn't work, my first debugging step for serial communications is to swap connections on pins 2 and 3. (Transmit and Receive data)

Since the TXD (3) of one side is connected with the RXD (2) of the other, this is indeed a null-modem cable. Normal serial cables have pins 2 and 3 connected straight through, and the DCE is responsible for cross-connecting them internally.
