The program file comm.exe is an augmented and rewritten version of the older Vcomm.doc or Virtual Communications Device Driver DOC. Some examples of communication devices that provide single asynchronous data streams are parallel port, serial ports, modems and fax machines. The comm.exe process file is a virtual communications driver or VCOMM which is a virtual device or VxD needed to manage each and every access to the system's communication devices. The file comm.exe is the core communications component in the Windows 95 Operating System. The process comm.exe may be started upon startup or manually.

The comm.exe application counts on port drivers which are separate virtual devices or VxDs to access the communication devices stated above. A port driver can be written to sustain a communications port that is not standard. Virtual devices or VxDs imitates a physical hardware component basically tricking the CPU in to thinking that a physical device exists when it really doesn't. For illustration purposes, let's say that software for fax machines can pose as a virtual printer. When the print option is selected, the document for printing is sent to a modem or fax which sends the information to another modem or fax machine or modem instead of an actual printer for printing the document.
