This chapter describes how to start and use the Comport program supplied with ReMapPro.
Comport 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, Comport can receive serial data from a COM port of your PC and then send them out to a TCP/IP network through a TCP/IP socket connection on your PC. Comport 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.
Comport makes serial data from your PC available on TCP/IP network and makes TCP/IP data available on serial ports of 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 Comport is running. You can connect to the remote serial port by connecting to a TCP/IP port. Comport can also be used to pass serial data across a corporate intranet or over the Internet.
You could connect a serial device to a COM port on your PC, run Comport and then connect to the device from any other PC on your network through a TCP/IP socket connection. This would allow you to use Telnet or any other TCP/IP communications software to read or write to the serial device directly from any PC located on the same network.
Over TCP/IP-based networks, Comport can function as a TCP/IP server or as a TCP/IP client. While running on your PC in the client mode, Comport establishes a connection with a remote TCP/IP server and then transmits and receives serial data to/from that server. While running on your PC in the server mode, Comport will establish a connection, and then transmit and receive serial data to/from a remote client upon the client's requests.
Comport can be installed on several PCs simultaneously. This allows you to attach a serial device to one PC, have Comport transmit the data across your TCP/IP network to a second PC where another instance of Comport would make the data available at a serial port. You can run Comport as a server on one PC in a network and then run a second copy of it as a client on another PC connecting back to the first copy. Any data that goes in the serial port on the server end will go out the serial port on the client PC and vice versa.
A terminal server is a device that connects a serial instrument to a network and provides an I/O path to the device through a TCP/IP port. You can configure Comport for several ports at a time and associate each serial port to a different TCP/IP port either as a TCP/IP client or as a server. Comport can perform the same function as a terminal server except it runs on a PC with a network adapter and one or more serial ports.
You can use Comport as a TCP/IP server with multiple COM ports on a single IP port (so that multiple modems could be used on the same IP port with auto-switching from one modem to the next).
With Comport, you can create "virtual COM ports" and use "the virtual serial ports pool" in your system. 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. The VSP pool can be used to supply any software application with COM ports (e.g., this is vitally necessary on some modern notebooks that do not have physical COM ports at all). This feature is available after installation of the VSP driver included in the package. With the VSP driver installed, you can configure Comport to map TCP/IP Ports onto virtual serial ports as well as to physical COM 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 use the virtual COM port driver on multi-processor and Hyper-Threading machines too.
