The main utility, VPortPro Client, included in the VPortPro package makes serial (RS232) data from your PC available on TCP/IP-based networks and makes TCP/IP data available on virtual serial ports of your PC (i.e., VPortPro Client can create virtual serial ports on your PC and redirect them to remote TCP/IP ports and vice versa).
VPortPro Client can also be used to pass serial data across a corporate intranet or over the Internet (using the Telnet protocol (with the features provided by the COM Port Control protocol specified by IETF RFC 2217) and the raw TCP connection protocol as well).
The COM Port Control protocol specified by IETF RFC 2217 can also be used for any serial device attached to an access server. Such devices could be: serial printers, plotters, monitoring devices such as pipe line monitors or medical monitors, general office equipment such as photo-copiers and cash registers, etc.
The Assistant Server is a software program designed to convert serial (RS232) data to the TCP/IP packets format and TCP/IP packets to serial data. While running on your PC, Assistant Server can receive serial data from a serial port of your PC and then send them out to a TCP/IP network through a TCP/IP socket connection on your PC. Assistant Server can also receive serial data from a TCP/IP network through a TCP/IP socket connection on your PC and send them to a serial port on your PC.
