ReMapPro Version 2.2 TCP/IP over COM port utility
The main utility, the Comport, is included in the ReMapPro package makes serial (RS232) data from your PC available on TCP/IP-based networks and makes TCP/IP data available on serial ports on your PC. This makes it possible for any other computer on the same network to send and receive serial data through a remote serial port on the PC where the Comport is running. You can connect to the remote serial port by connecting to a TCP/IP port. The Comport can also be used to pass the serial data across a corporate intranet or over the Internet. The Comport allows multiple sessions to run simultaneously but each with a different serial port.
The Comport supports full two-way I/O for full control of serial instruments (i.e. any instrument that you can plug into the serial port (RS232, RS422 or RS485) of your PC). Typical devices include most serial devices like gauges, scales and balances, sensors, micrometers, calipers, bar code scanners, densitometers, laboratory instruments, electronic balance or electronic measuring instrument, RF equipment, communication systems, etc...
