Description
The Null-modem emulator (com0com) is a kernel-mode virtual serial port driver for Windows. You can create an unlimited number of virtual COM port pairs and use any pair to connect one COM port based application to another. The HUB for communications (hub4com) allows to receive data and signals from one COM or TCP port, modify and send it to a number of other COM or TCP ports and vice versa.

64-bit Windows requires all drivers to have a valid digital signature. Com0com does not, so the driver is unavailable for use by 64-bit Windows 7. The ReadMe file says, The com0com.sys is a test-signed kernel-mode driver that will not load by default. To enable test signing, enter command: bcdedit.exe -set TESTSIGNING ON and reboot the computer. NOTE: Enabling test signing will impair computer security. This must be done by an administrator, as installation must be.
