           COM port to TCP redirector (com2tcp)
           ====================================

INTRODUCTION

The COM port to TCP redirector is a Windows application and is a part of the com0com project.

In conjunction with the Null-modem emulator (com0com) the com2tcp enables to use a COM port based applications to communicate with the TCP/IP based applications. It also allows communication with a remote serial port via the TCP/IP.

The homepage for com0com project is http://com0com.sourceforge.net/.

BUILDING

Start Microsoft Visual C++ 2005 with hub4com.vcproj file. Set Active Configuration to "com2tcp - Win32 Release". Build com2tcp.exe.

EXAMPLE OF USAGE

You have old TERM95.EXE application from the Norton Commander 5.0 for MS-DOS and you'd like to use it to communicate with your.telnet.server telnet server. You can do so this way:

  1. With the com0com driver create a virtual COM port pair with port names COM2 and CNCB0 (see com0com's ReadMe.txt for details).

  2. Start the com2tcp.exe on CNCB0 port. For example:

    com2tcp --telnet \.\CNCB0 your.telnet.server telnet

  3. Start the TERM95.EXE on COM2 port.
