From TALtech: TCP-Com is a software based RS232 to TCP/IP converter. TCP-Com allows any of the RS232 serial ports on your PC to interface directly to a TCP/IP network. For example, you can use TCP-Com to turn a PC into a 'Serial Device Server' so that you can connect any RS232 serial device directly to a TCP/IP network and communicate with that device from any other workstation in the same network or across the Internet. TCP-Com can also create 'Virtual' RS232 serial ports that are actually connections to a TCP/IP port. This allows you to use existing Windows based serial communications software to send and receive data across a TCP/IP network.
