Com Port Redirector
The Com Port Redirector allows any PC running the Microsoft® Windows® operating system to
use ports on a network server as if they were connected directly to the PC. The Redirector
creates a virtual COM port within Windows, which for most purposes acts just like the selected
serial port on the server. Whenever this virtual port is accessed, the redirector forms a network
connection to the server, and routes all data between the physical serial port on the server and
the virtual port within Windows. This allows a modem on a server to be shared by many PC
users, thus the name of "modem sharing" which is commonly used to describe this.
The Redirector support both IP and IPX. For IP, you must have IP installed and bound to your
network card, and a server which supports TCP socket connections to its serial ports. For IPX,
you must have IPX/SPX installed and bound to your network card, and the server must support
IPX/SPX connections to its serial ports.
