Background information:

The Com-Server compact version provides everything you need for direct connection of a serial port to the computer network. All protocols are included in the delivery (see text box and applications included with the product data sheets). Instead of the standard RS232 port, a number of different port modules may be used. The serial and the network parameters are configured via Telnet and RARP or ARP.

Com Port Redirector:

The W&T COM Port Redirector for Windows 9x/NT/2000/XP/2003 also gives serially operating Windows programs the ability to communicate over the network. Virtual COM ports are installed on the system which behave like standard COM ports with respect to the applications. Communication with the terminal device is now however over the network and a Com-Server (data sheet with download link).
