The Null-modem emulator allows you to create an unlimited number of virtual COM portpairs and use any pair to connect one COM port based application to another.Each COM port pair provides two COM ports. The output to one port is the input from otherport and vice versa.
The Null-modem emulator can be used to provide serial interface for device emulators.In this case the device emulation program uses one port of the pair andthe other port can be used by Windows or DOS application thatrequires a COM port to communicate with the device.For example, to send/receive faxes over IP you can connect WindowsFax application to t38modem (T38FAX Pseudo Modem ,part of the t38modem project ) via virtual COM port pair.
The Null-modem emulator can be used to provide serial interface for COM port redirectors.For example, with the com2tcp (COM port to TCP redirector,part of the com0com project ) you can communicate via serial interface with the TCP/IP servers.If you feel that com2tcp is what you need but can't find some required features (for example RFC 2217 support) then try use hub4com instead.
With the hub4com (HUB for communications,part of the com0com project ) it is possible to handle data and signals from a single serial device by a number of differentapplications (for example, several applications can share data from one GPS device).It's also possible to use the real serial ports of remote computer like if they exist on a local computer.
You can find more information inUsing com0com and com2tcp,ReadMe.txt for com0com,ReadMe.txt for com2tcp,ReadMe.txt for hub4comand onSourceForge Projectpage.
Alternatively, you can use Virtual Serial Port Driver by Eltima Software. It allows creating a large number of virtual COM ports and gives you great possibility to emulate serial port behaviour fully. Virtual Serial Port Driver provides flexible port creation, management, and removal, allows testing the software, supports control lines and high speed of data transfer with virtual port.

I will give an example of installing or updating ixgbe drivers on Linux.
Let's see the current version (for example, in Ubuntu Server 16.04 for HP 560SFP+, the ixgbe 4.2.1-k version was installed by default):
Download the new drivers from the official site
https://downloadcenter.intel.com/download/14687/Intel-Network-Adapter-Driver-for-PCIe-Intel-10-Gigabit-Ethernet-Network-Connections-Under-Linux-
or
https://sourceforge.net/projects/e1000/files/ixgbe%20stable/
Or a patched version of the driver for the correct distribution of network board interruptions across the processor core when using QinQ
https://github.com/serhepopovych/ixgbe/tree/ixgbe-5.6.3/double-vlan
Or:
Install the necessary components in the system:
Using the commands below we install the driver, I note that if the Linux kernel has been updated, then we will reboot the server before installing the driver (the module is usually written in /lib/modules/KERNEL_VERSION/updates/drivers/net/ethernet/intel/ixgbe/ixgbe.ko):
The error below can be ignored, it just means that make cannot find the keys to sign the driver:
SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:175
After installing the driver, any of the commands will unload the old driver module from memory:
And load the new one you just installed:
Download Vyacheslav Frolov Others Drivers
Check the version:
In order for Ubuntu to load a new driver at system startup, and not the old one, do:
For RedHat:
If necessary, specify the network interface IP address (the name of the network interface can be seen, for example, in the logs by typing the command 'dmesg -T'):
I note that on some versions of the drivers the occupied RAM space can quickly increase, usually it becomes noticeable in the graphs after a day or a week. Stable versions in which no memory leaks were noticed were 5.6.3 and 5.3.8.
If it grows, then you can, for example, unload and load the ixgbe module to understand if it has a problem (attention, the connection to the server will disappear):
To support third-party SFPs, you may have to load the module with the option:
So that when the system starts, the driver also loads with this option, we specify in the /etc/modprobe.d/ixgbe.conf file:
And also in the file /etc/default/grub, specify:
Apply the changes:
