COM to TCP IP Software, TCP-com. Redirect COM port Serial (RS232 or USB) data to TCP IP Networks.

Redirect serial COM port data to TCP IP networks using TCP-Com software from TALtech. TCP-Com is a Serial Port Redirector Software sending COM port data over TCP IP networks such as Ethernet or Internet.

Redirect COM Port Device Data over TCP IP Networks

Use TCP-Com as a PC-based Serial Device Server (also known as a Terminal Server) to make any RS232 COM-port connected devices accessible on a TCP IP network (i.e. Ethernet).

Attach devices to your PC’s RS232 or USB COM ports and TCP-Com will redirect the data to a TCP IP address (and port number) on your TCP network. Add additional USB or RS232 COM ports to your PC to make TCP-Com act as a multi-port Serial Device Server (or Terminal Server) if you need many serial COM port connections.
