The module is a single-slot, backplane-compatible solution. Each port is capable of sending and receiving large ASCII character strings or byte streams of up to 4096 characters or bytes. Many different serial communication devices can be integrated into the ControlLogix platform by building upon the sample ladder logic provided for this module.
Peripherals are devices that are attached to a computer system to enhance its capabilities. Peripherals include input devices, output devices, storage devices, and communications devices.
All peripherals must have some way to access the data busof the computer (the communications channel on the motherboard that connectsthe processor, RAM, and other components). To do this, peripherals are connectedvia some kind of port (also called a I/Oport, forinput/output) on the computer (and a cable with the proper connectors is needed).

Hi, yes it has a AP9617 NIC in the smart slot. That is why I'm trying to connect in the first place as I need to reconfigure it. I'm using a 940-1524D serial cable, and have now tried baud rate 2400, data bits 8, Stop bits 1, Parity None, Flow Control None.
In some cases, the controller chips and circuitry for a port may be included on the motherboard itself (especially in laptop computers). In other cases, an expansion card in one of the expansion slots on the motherboard provides the needed port. This card is also called a controller card or an interface card. The software needed to handle the interface through the controller card is called a device driver, a type of system software.
Serial Port Stopbits
A video card that allows output to be sent to a monitor is an example of an interface card. The part of the video controller card that protrudes through the case of the computer includes a port (or ports) that monitor cables can connect to.
Let’s look at some of the kinds of ports used on personal computers.

The serial port is a type of connection on PCs that is used for peripherals such as mice, gaming controllers, modems, and older printers. It is sometimes called a COM port or an RS-232 port, which is its technical name. If that's not enough to confuse you, there are two types of serial ports -- DB9 and DB25. DB9 is a 9-pin connection, and DB25 is, you guessed it, a 25-pin connection.

A serial port can only transmit one bit of data at a time, whereas a parallel port can transmit many bits at once. The serial port is typically the slowest port you'll find on a PC, if you find one at all. Most newer computers have replaced serial ports with much faster and more compatible USB ports.
