VPortPro is a System Utilities::File Converters software developed by Labtam Inc.. After our trial and test, the software was found to be official, secure and free. Here is the official description for VPortPro: The VPortPro Client 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, VPortPro Client 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. VPortPro Client 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.
VPortPro Client supports two transport data stream protocols:
- Raw TCP
- Telnet (with the features provided by the COM Port Control protocol specified by IETF RFC-2217)
VPortPro Client functions as a TCP/IP client (for both the protocols), i.e. it will initiate and establish connection with remote systems (by sending connection requests), and then communicate with connected TCP/IP servers. As a TCP/IP client, VPortPro Client allows to establish connection to a single TCP/IP server for each serial port. Normally any data received through the TCP/IP port that it connects to will be transmitted out the serial port and any data received through the serial port will be sent back to the TCP/IP server. This enables fully bi-directional communications. So, VPortPro Client redirects COM port to a TCP/IP port and vice versa.
Also with VPortPro Client, you can create "virtual serial ports". A virtual serial port (VSP) appears to application software as a "standard" MS Window's communications port (virtually identical to an RS-232 port). Data may be written to VSP by applications, and data may be read from VSP as though it were a standard COM port. You can configure VPortPro Client to map TCP/IP ports onto virtual serial ports. This allows MS Windows applications to generate or consume data to and from VSP as though the data were being processed by physical hardware. you can download VPortPro 2.6 free now.
