This topic of how to use USB-to-Serial-Cable to connect devices rs232 ports to your laptop is one area that will bring relief to many people out there. If you have devices that connect to the rs232 port to perform a special task such as; software upgrade, or data transfer, then this post is for you. Such devices include decoders, cell phones, PBXs, routers, PDAs, Cameras e.t.c.
If you own a desktop computer from the 80s, chances are high that it comes with a 9-pins rs232 port by default. However, modern desktop computers and laptops don’t come with one. This is not to say that you can’t use a serial port on a laptop. A USB to serial adapter comes in when you need to use the serial port capability of your windows or mac computer
Going forward in this article, I will introduce to you a modified and easier to use a version of A USB to SERIAL ADAPTER. The good news is that I have tested it on both my Dell laptop and a Mac computer with good results. The latest version supports all architectures of windows(both 32 and 64 bits) as well as all windows and mac version.
How does a “USB to SERIAL Adapter” Works
Many of today’s new computers come “legacy-free”, which means they have no serial or parallel ports. “The BAFO BF-812 (DB9)“( As the name of the one is using which I also recommend for all is called) will help you solve this problem by adding serial connectivity via a USB port. Now with “The BAFO BF-800 (DB9)”, you can connect all your legacy( I mean all your devices that comes with 9 pin serial ports like PDAs, cell phones, Digital camera, digital receiver, GPRS dongles) to your new computer.
In other words, you can easily use your laptop to restore your dead satellite decoders, routers, phones, digital cameras e.t.c.

How to use USB-to-Serial-Cable: Installing the drivers to your Computer
Installation is very easy and it is more or less like a plug and play. As long as your computer drivers are updated. Once you connect the device, one end to your com-port and the other end to the device, your computer will quickly detect it as a COM Port as shown below.
For my experiment, I updated the firmware of a satellite dongle and it worked perfectly. In my case, my computer assigned COM PORT26 to my device as shown below. The number of the assigned com can be anything so it doesn’t matter.
Basically, once the adapter and your device are properly connected to your computer, you can detect your com port without opening any tool. All you need to do is to simply go through the followings:
right-click on your computer>>properties>>device mananger>>Ports >> the locate the Com port number. For further clarification, see the image below:
How to Properly Connect your Device to a USB to Serial Adapter
The image below depicts how you can correctly connect your device(in my own case a satellite receiver) to a laptop computer via USB to serial adapter.
Using the com port is pretty easy. Just select it from within the PC Suite/loader of the connected device and follow the individual instructions peculiar to your device.
It doesn’t matter the device, one your computer detects the adapter, your problem is half-solved. As a reminder, sometimes, you need to use the pc loader to restore some devices especially the one with serious software problems.
