TCP/com is a very simple program and we do not have any tech issues or notes for it. It is designed to make RS232 serial data available at a network IP address or make TCP/IP network data available on a serial port. The on-line help in the program should be more than adequate for explaining how to use the program.

The only issue that we commonly run into is confusion as to what you can do with TCP/Com. We are often asked is TCP/com can "Virtualize" a serial port. Users have existing software that communicates through a serial port and they want to get data from a TCP/IP network port address into that software. In other words, they want TCP/IP data to appear as if it were being transmitted and received through a "Virtual" serial port so that their existing serial communications software talk to a TCP/IP port. TCP/com does not do this. It transmits and receives data through a real serial port (i.e. com 1, com 2, etc.) and does not create a virtual one.

You can use TCP/Com to accomplish this type of functionality however the trick to doing it is to use two serial ports with a Null modem cable connecting the two serial port to each other. You would run TCP/Com on one serial port thereby linking that serial port to a TCP/IP port and then you would run your existing serial communications software on the other serial port. When data is transmitted from the serial communications program, it would go out its serial port and then immediately back in the other serial port into TCP/Com which would then send the data out the TCP/IP port. Data coming in the TCP/IP port would likewise go out the serial port that TCP/Com is running on and immediately back in the other serial port to the serial communications program.

If you are looking for software to create a "virtual" serial port that is really a connection to a TCP/IP port, please visit http://www.tacticalsoftware.com . They sell a program called DialOut/IP that is designed specifically for this purpose.
