This is a free piece of software for 32 bit Windows operating systems.There is also a paid version for 64 bit platforms.
Vspe Virtual Serial Ports Emulator 32 Bit Windows Operating![]() This software allows you to create virtual COMs on your PC (COM1, COM2, COM3, etc.) which, in reality, refer to a specific IPTCP port. We can use a numerical IP address (if we use a SIM with a fixed IP address, or because we obtain the actual IP address by SMS or a missed call), or we can use a DNS (if we use the DynDNS service for example) We also select the TCP port in which MTX-Tunnel is connected to (the default is 20010). Finally, we select the virtual COM port that we previously created (in our case COM10). Remember that the configuration of the modems serial port (bauds, number of data bits, etc.) must be established in the modems configuration file config.txt, as indicated in this manual.

Developers creating software to work with industrial devices need to test and debug applications before releasing them. Does anyone know of a way to create a fake serial port and control it on Windows XP BefittingTheorem BefittingTheorem 5 Answers If you are developing for Windows, the com0com project might be, what you are looking for. It provides pairs of virtual COM ports that are linked via a nullmodem connetion. You can then use your favorite terminal application or whatever you like to send data to one COM port and recieve from the other one. EDIT: As Thomas pointed out the project lacks of a signed driver, which is especially problematic on certain Windows version (e.g. Windows 7 x64). There are a couple of unofficial com0com versions around that do contain a signed driver. One recent verion (3.0.0.0) can be downloaded e.g. Frank Bollack Frank Bollack I know this is an old post, but in case someone else happens upon this question, one good option is Virtual Serial Port Emulator (VSPE) from EterlogicIt provides an API for creating kernel mode virtual comport devices, i.e. However, some of the advertised capabilities were really not capabilities at all. Product options include both desktop applications, as well as software development kits with APIs. However, as other posts here have pointed out, there are other options. Vspe Virtual Serial Ports Emulator Windows 7 X64 ToHere is a list of various serial utilities: com0com (current) com0com - With Signed Driver (old version) and, yet another place for com0com with Signed Driver (Petes Blog) Tactical Software Termite COM Port Serial Emulator Kermit (obsolete, but still downloadable) HWVSP3 HHD Software (free edition) ryyker ryyker I use com0com - With Signed Driver, on windows 7 x64 to emulate COM3 AND COM4 as a pair. Then i open COM3 with the app im developping (c) and send data to COM3. The data sent thru COM3 is received by COM4 and shown by COM Dataport Emulator who can also send back a response (not automated). So with this 2 great programs i managed to emulate Serial RS-232 comunication. Hope it helps. Both programs are free Jhollman Cutcsa Jhollman Cutcsa Another alternative, even though the OP did not ask for it: There exist usb-to-serial adapters. Depending on the type of adapter, you may also need a nullmodem cable, too. That way you can work directly with the sensors, and you do not have to try and emulate data. That way you are maybe even save from building an anemic system.(Due to your emulated data inputs not covering all cases, leading you to a brittle system.) Its often better to work with the real stuff. Purchase two USB to serial converters, and connect them via a NULL modem. Pro tips:1) Windows may assign new COM ports to the adapters after every device sleep or reboot.2) The market leaders in chips for USB to serial are Prolific and FTDI. Both companies are battling knockoffs, and may be blocked in future official Windows drivers.

COM ports have been introduced a long time ago and have been an integral part of computers. These days however they become almost obsolete as more and more machines use USB ports or no ports at all. This doesnt eliminate the need for serial connections though, especially if we are talking about industrial equipment, lab devices, etc.
