OVERVIEW 

VCOM is a serial-to-IP redirector driver and configuration utility for Microsoft

®

 Windows

®

 XP and 

Windows 2000. Using this utility, you can create a virtual communication (COM) port and 
associate it with a network device that has a known Internet Protocol (IP) address. 
 
The VCOM driver allows a LAN host computer to assign a virtual COM port to a remote device. 
Once configured, this allows applications that communicate through COM ports to use a TCP/IP 
network, without requiring changes to the application. This driver is designed specifically to 
provide LAN connectivity for the AirborneDirect™ Serial Bridge.
