VSPE (Virtual Serial Port Emulation) is a free software for 32 bit Windows operating systems. There is also a paid version for 64 bit platforms.
This software can be utilised to allow legacy device software to connect to serial devices that only allow connections via a COM serial port, such as some data loggers, load cells etc. This software allows for the creation of virtual COM Ports on your PC (COM1, COM2, COM3, etc.) that are linked to a specific IP/TCP port.
