Transfer files easily: Your guide to using null modem cables

Be it playing games or running applications, every task feels exciting with a new computer. However, there comes a moment when you realise you’ll have to move all your files. From pictures to documents, transferring everything alone feels like a daunting task. Sometimes bribing your friends doesn’t help either. Isn’t that right?

Well, worry not, because these days there are various ways you can transfer files easily and quickly. One such method involves using null modem cables.  Knowing how to transfer files is crucial, whether you have large files to move, small files or some private, valuable data. To help you and save you time, here is everything you need to know. 

Transferring Files Directly Using Null Modem Cables 

Looking for a straightforward process to transfer files directly between two computers? This is where null modem cables come in and here is a detailed guide to the process:

1. Hardware/Software Requirements

The very first step is to gather the hardware and software you’ll need for transferring files. This includes:

• 2 computers with serial ports

• A null modem cable 

• Serial communication software

1. Connect the Cable 

Now you must locate the serial ports on both your computers. On Linux machines, they are labelled as “ttySO” or “ttyS1” and on Windows machines, they are labelled as “COM1” or “COM2”. 

Next, take the null modem cables and connect one end to the serial port on the first computer and the other end to the serial port on the second computer. 

1. Configuration 

Now you must configure the serial connection by opening the serial communication software on both computers. Then set the baud rate, parity and data bits. Once done, stop bits to match on both computers. Typically these settings are as follows:

• 9600 baud 

• 8 data bits 

• No parity 

• 1 stop bit 

Once done, now you must set the serial port. 

1. Transfer Files

To transfer files smoothly, use the serial communication software to initiate a file transfer on the computer sending the file. While on the computer receiving the file, use the serial communication software to accept the file transfer. Using the null modem cables, the files will be transferred within no time directly between the two computers. 

Are null modem cables reliable?

Doubting if you should buy null modem cables? Worried about if they are not reliable? Well, don’t because these cables offer several benefits. This includes:

• They transfer files at speeds of up to 115.2 Kbps, allowing fast and smooth transfers of files. 

• They ensure a reliable connection, thereby minimising data loss or corruption risk. 

• Because they don’t require a network connection, they offer convenience and ease of use. 

• These cables are simple to set up and easy to use. 

• Transferring files using these cables is a hassle-free process as they don’t require any special drivers and software. 

• These cables minimize eavesdropping, thanks to the secure and private connection they maintain between two computers. 

• Because these cables don’t consume energy, they promote an environmentally friendly way to transfer files. 

• These can also be used repeatedly, ensuring no electrical waste. 

• Compared to other file transfer methods, these are relatively a cost-effective solution. 

Other Ways to Transfer Files Directly Between Two Computers

In addition to using a db9 null modem cable, here are some other ways you can transfer files directly between two computers:

1. Using an External Hard Drive

You can transfer files using an external hard drive which is a physical storage device. Depending on the drive’s capacity, you can transfer a few files as well as huge contents. It is an ideal way to transfer files for those who lack the time to download or install transfer software. They allow direct and quick transfer without the need for an internet connection.  

1. Data Transfer Cable

Another way you can transfer files directly between two computers is by using a data transfer cable. Using this, you don’t have to insert and then eject a device, thereby saving yourself from the hassle. However, when transferring files, make sure your both computers are placed nearby and are switched on. 

1. Cloud Storage

Looking for a more efficient way to transfer files between two computers? Opt for the cloud storage way. Unlike manual transfers or using a db9 or db25 null modem cable, it makes accessing and sharing files easier. Because no external storage devices or cables are needed, they are considered the most convenient options. You won’t also have to worry about data loss as every file transferred is secured through data encryption.  

1. Using a Dropbox Backup

Another method of transferring files is through a Dropbox backup, which is a backup service. It eliminates the need for slow manual connections, as you can easily transfer with just a few clicks. 

1. Migration Software 

Do you need to transfer everything to your new PC? With the help of migration software, this is possible. It allows handling huge amounts of data and maintains the security of your files.

What to Do After Transferring Files Between Computers

After moving your files, make sure to keep your old computer for a few weeks in case you forget something. Make sure all of your data and personal information are deleted. This is crucial if you decide to sell, throw away or donate your old computer. 

You can also use free data destruction tools if you want to leave no trace or data on your old computer. This is important because you never know who still wants to obtain your personal details such as previous emails or bank account details. 

Enjoy Hassle-free Transfers without any Interruption

Want to avoid your monthly subscription to cloud service? Transferring files from one computer to another using null modem cables is a great choice here. These cables work faster than an external hard drive. Despite the various ways to transfer files directly between computers, you can only transfer the data you can access. This means your documents and other valuable data will be safe, even if your computer is stolen.
