TCP-Com is a software based RS232 to TCP/IP converter. TCP-Com
allows any of the RS232 serial ports on your PC to interface
directly to a TCP/IP network. For example, you can use TCP-Com
to turn a PC into a Serial Device Server so that
you can connect any RS232 serial device directly to a TCP/IP
network and communicate with that device from any other workstation
in the same network or across the Internet.
TCP-Com can also create Virtual RS232 serial
ports that are actually connections to a TCP/IP port. This
allows you to use existing Windows based serial communications
software to send and receive data across a TCP/IP network.
TCP-Com can also be configured to run as a Windows Service
so that it loads and runs automatically even before a user
logs onto the workstation where you run it.
TCP-Com is an extremely simple program however it is also
extremely powerful and can be used to solve a wide variety
of device interfacing and RS232 or TCP/IP communications problems.
A brief description of some common applications are listed
Use TCP-Com as a multi port serial device server.
Instead of purchasing hardware based serial device servers,
use a PC and TCP-Com to do the same job. TCP-Com supports
connections to up to 256 COM ports in a single PC so you can
create a serial device server that supports up to 256 RS232
Use TCP-Com to create Virtual COM ports that connect to
serial device servers (or to any TCP/IP port).
The ability to create Virtual COM ports with TCP-Com makes
it possible to use existing serial communication software
to send or receive data through a TCP/IP port. This includes
the ability to connect to and communicate with any serial
ports exposed by another copy of TCP-Com running in a different
workstation where it has been configured to work as a serial
device server. You can also create virtual COM ports that
connect to hardware based serial device servers available
from a number of different manufacturers. In both cases the
Virtual COM ports behave as if they were local serial ports
installed directly in your PC. This means that you can use
existing serial communications software to open a serial port
on a different workstation in your network (or across the
Internet) or to open the serial ports on a hardware based
serial device server connected to your network.
Use TCP-Com to allow more than one RS232 serial communications
program to open the same COM port simultaneously.
Normally Windows will not allow two serial communications
programs to open the same serial port at the same time however
it is possible to use TCP-Com to feed data from a physical
RS232 serial port to multiple Virtual serial ports
so that more than one application program can input data from
the same physical RS232 serial port simultaneously.
Use any TCP/IP network (including the Internet) as a giant
Run TCP-Com on one PC configured as a TCP/IP server and run
another copy of it on another PC as a TCP/IP client connecting
to the first copy of TCP-Com (the server). Any data that goes
in the serial port on either PC will go out the serial port
on the other PC and vice versa.
Use TCP-Com to map a TCP/IP port to a different TCP/IP
port either as a client or as a server.
Run one instance of TCP-Com configured to create a virtual
COM port and connect that virtual port to a TCP/IP port. Then,
configure a second instance of TCP-Com in the same workstation
to open the virtual COM port created by the previous instance
of TCP-Com and connect to a different TCP/IP port. Any data
that goes in either TCP/IP port will go out the other TCP/IP
port and vice versa.
