Commercial 05 Jul 2006 Description AVSD OEM is a programming interface, which allows you to add support of virtual serial ports to your own application. You have full control over ports created with the help of AVSD OEM, including reading data that some other application has written using WriteFile function, writing data to be read with ReadFile function, flow control signals monitoring and controlling. If you have the software, which works with some device connected to COM port and you want to capture all the data that goes to and from the port, then AVSD OEM is what you need. Just create one virtual port and tell the application to use it. Now you can monitor all data that application writes to the port and redirect it to the real COM port. And vice versa, you monitor all data coming from device and redirect it to the virtual port. With AVSD OEM you can: • Create your_protocol-to-serial abstraction.

• Create virtual platform and emulator plugins. • Create usb2serial, bluetooth2serial, IrDa2serial adapters.

Shareware 05 Jul 2006 Description Software developers can access various devices by utilizing the Windows API. When using an API, you gain access to a full spectrum of available features, but API programming is a very tough and time-consuming task. You have to study the documentation and you have to create all the high-level functionality based on the low-level API functions from scratch. This is OK if you develop a specialized application.

However, in most cases, you just want to get a certain device working in your program with the least effort possible. One of the system devices that you often need to support is a Serial Port. There are numerous lab instruments, protection gadgets and other inventory that can be connected via a COM port. Instead of spending weeks or even months for API coding, you could use a ready-made ActiveX component in your program. We recommend you give Serial Port Control from FabulaTech a try. Serial Port Control is an inexpensive, royalty-free, ActiveX component. You can use it with any ActiveX-enabled development environment, such as Visual C++, Visual Basic, Delphi, etc.

Just put it on a form and you have all the functionality you need to access a serial port, either physical or virtual. Serial Port Control automatically enumerates all the ports available in the system. You just need to select the port name you wish to work with. The event driven architecture of this component is a snap to use. You don't have to check ports periodically in order to find if there is new data available for reading from a port. Simply define a function in your program that will be triggered automatically by the appropriate event and process the data. Despite its low cost, the component is royalty-free.

There are no hidden fees and you are free to distribute it together with your own software. Informations • Status: Trial (work while IDE is running) • Source: None • price: $99.95 • Size: 543kB Platforms: C2k6, CB3, CB4, CB5, CB6, D2005, D2006, D3, D4, D5, D6, D7.

>>>>Using a PC's parallel port for more than printers This material is about the parallel port on MS-DOS / Windows computers. It sometimes spills over into things of more general nature when talking about devices you might attach to the parallel port. In a moment, I am going to ask you to consider if the parallel port is really the way you want to go, and suggest alternatives. PLEASE NOTE: You CAN damage your computer if you make ill-advised connections to it. Any use you make of anything you find here must be AT YOUR OWN RISK I have designed a that may be of interest.

(Click on the link for information, and a way to obtain the circuit diagrams.). For a free 'turn parallel port pins on/off' program, which works with Windows XP (and other Windowses, I think) check out my.

Also, as part of my Delphi tutorials website, I have posted another small app to turn individual pins of the parallel port on or off. You can that goes with.

The app is in the.zip. You don't need to be a Delphi programmer to use it. But you do need to put both the app (DD79.exe) and the dll called 'InpOut32.dll' in some folder on your system. They should be in the same folder. For any: A good site with essentials, minimal warnings, fewer details. (Not written by me. Opens in new tab, so you can come back here if disappointed.)

•, with Basic, Pascal and Delphi addressed. •, for the complete beginner. (Opens in new tab) •, for beginners. •, pull ups, pull downs. • Notes on interfacing.

• Fine for printer, maybe. AND a, for whatever I've missed! Odds and ends.

Before we get to the parallel port stuff, two ads from our sponsors. 1) If you are going to use this page, you are probably not a computing novice. Ever set up a web server? It isn't hard! If you have an always- on broadband connection, FarWatch may be of interest. I have written explaining how to use an old Win98 box (or better) to give yourself a way to monitor the premises the old Win98 box is at from anywhere on the internet.

Nothing to buy! And if you connect something to that PC via it's parallel port, you can 'see' the state of the inputs to the parallel port from afar, too. 2) If you would be willing to help bring this information about the parallel port to a wider readership, please check out?

Don't want to tie up your printer port? You can get a cheap card to provide a second parallel port! Alternatively, for some projects needing input only consider using your joystick port. It can detect 4 switches and 4 resistances. (N.B.: Most joystick ports do not sense analogue voltages.) For how to program Delphi 2 and higher to read joysticks visit Using your PC isn't the only way to have a lot of fun with controlling and sensing external devices, for example the, which is itself open source, and which has excellent free, open source development hardware. (Control Plus) once sold a neat little Pascal based microprocessor system, and they offered a free simulator.

If you hear of that being available again, please tell me? If for some reason you don't like the Arduino,. Don't let the warning above worry you too much. I want to stress that there is a lot of fun to be had with electronics projects. Find yourself an 'antique' PC.

If you can't rescue one from a dusty corner, you can buy one for almost nothing. You can use the same monitor as you use on your main machine. If you wreck the antique, it hasn't cost you much! (I got one, with monitor, off a sidewalk once!) I have a third generation. You interpose it between your PC and the home-made stuff you are attaching to the parallel port, and any mistakes in the home-made things are blocked off from the computer by opto-isolators and relays. (Inputs to the computer are passed through an opto-isolator, outputs are fed to the coils of relays.

Properly set up, the worst thing you can do is wreck an opto-isolator or a relay. Both relatively hard to do!) Email me if you are interested in that device.

If you can design and etch your own PCBs I can send you some notes. (Send me a snailmail address, as they are not available in machine readable form.) If you are not making your own PCBs, I may still be able to help, but not so quickly and not for free.

If you are very new to the hardware side of computing, my may be of interest. Alternative ways to have the fun we used to have via the parallel port If you are sure you just want to know how to do it with a parallel port, without considering the alternative connection paths, you can Once Upon A Time.

It was quite easy even for a mere enthusiastic amateur to connect external electronic bits and pieces to a PC. Many of us started with LEDs (or even incandescent bulbs. There WAS a time before LEDs!). Then there were push buttons. It wasn't only output that was possible. And once you got started, the sky was (and is) the limit. There's a saying: The hard part is thinking of what you want to do.

In other words, the hard part is finishing 'I'd like to make the computer control/ read. ' It is still quite possible to do these things. But it isn't quite as easy today. If you are just getting started, I would advise you to consider other ways of doing the things we used to do via the parallel (or serial) port. They won't be suitable for all of you, nor for all projects, but at least consider them.

And when I've listed them, I will go on to talk in detail about how to use the parallel port, for those who want or need to do it that way. You can now (2010) buy into for not very much money and perspiration. I particularly like the Arduino, but there are many alternatives. (I have an Arduino-specific page which you can access from the microprocessors page there is a link to above.) Once you master the basics. Not rocket science.

You can use an Arduino, or similar system the way we used to use a PC and its parallel port. Life becomes fun again, instead of being work. Once upon a time, I had a whole PC tied up just to run a burglar alarm at my house. Now the same work can be done with an Arduino. The Arduino costs MUCH less, uses less electricity, is more tolerant of the occasional power failure. And has other virtues, few vices.

Another cool possibility: You can connect one or more! 8 bit input/ output ports to your PC using the Dallas Microlan, aka '1-wire'.

Look at the DS2408 if you are impatient. Or, give a try.

Extra cool: The ports would interface to your computer via provided-by-others software running through either your serial port or your USB port!! (You still have to access the software that accesses the ports, but a lot of the overhead of the communications with the port is taken care of for you.) The bad news? You need to equip your PC with a pc-to-MicroLan adapter (about $25). The data rates wouldn't be as high as they could be via a PCs parallel port. But they will be high enough for many designs.

You will need more advanced programming skills to use the 1-Wire 'answer'. Digital I/O over a LAN, or even over internet: We are now moving into a more expensive and less flexible realm, but there are ways to have digital I/O pins (what a parallel port gives you) connected to a PC across a LAN that the PC is part of, or even across the internet, if you are willing/ able to set up a server near the device with the I/O pins. I don't have extensive information for you in this area, but I do have some.

See my pages starting with. There's also my FarWatch system, which is not expensive, for what it does, but doesn't offer you all the possibilities of what you can do via the parallel port. You can check temperatures, switch closures, etc.

Download Dreamweaver Cs6 Crack Keygen Download. You can even have graphs of the state of the monitored phenomena. The Arduino, already mentioned, is one way into the delightful world of digital electronics.

If you are already in that world, you might consider at least the following two 'answers' to the sorts of things we used to do with a PC and its parallel port. There is a PIC microprocessor from MicroChip with built in USB services. It looks like a neat device for all sorts of things.

I haven't played with it personally, but know people who have. It looks like it shares many of the Arduino's virtues.

I suspect you need a little more experience or determination to get started with it, and creating your own USB devices will never be trivial, but if you want to give it a try, you should look into the PIC 18F4550. The looks like a fine solution to the hardware issues. ($38 at 2/10) Another possible route: If you are into making your own electronic devices, you might be interested in the USB modules from.

I wrote the next paragraph a while ago. And now (3/10) am not sure what device it describes! I think it is the FT2232H from FTDI, but I'm not sure, and after 15 minutes of struggling around their site, I've given up trying to find what I saw previously, somewhere. If it sounds good to you, do go to FTDI's site.

I think you will be rewarded! For about $20, you can buy a little unit that plugs into a Win98 or higher machine via USB. On the 'outside world' side, it has 8 bi-directional digital input/ outputs, and a few handshake lines. The programming isn't trivial, but there is great material about accessing the device. Illustrations in Delphi are provided. You either install a TComPort component (a freeware one, with Delphi source code is available from and then access the 8 bits as if (to Win98) they were on a COM port, OR you use a DLL (supplied royalty free from FTDI). It is not exactly a parallel port via USB, but that's roughly the idea.

ANOTHER 'answer (!!): There are now devices which might be called 'parallel ports on the LAN'. And if you can access something on a LAN, you're not far off being able to access it across the internet, too, if you want to.

Turn up your home's heating via the internet as you shut down your PC at work at the end of the day? One source of interfaces accessible across LANs is. That link will take you to the product page of their, to adapt their online text. Webserver based IO control module Key Features - Remote I/O Monitoring and Control with Ethernet - 8 Digital Input Ports - 8 Digital Output Ports - 2 Analog Input Ports (12 bit resolution) - 2 Analog Output Ports (12 bit resolution) - Supports Application Program - Supports WebServer I found several suppliers (search with Google for 'WIZ220IO') selling it for a little under $40 (6/10).

And so, at last, to Doing It With A Parallel Port. If you haven't been convinced to use one of the alternatives above, that is! Extended explanations appear further down the page Software. For a simple program to turn bits on or off just by clicking a button, go to.

There are free programs there. Some for, including one for via the parallel port, or via a joystick's 'fire' buttons. To send 123 to the parallel port. Polythene Feeder Rar Extractor there. (There are notes below about obtaining Delphi) Once upon a time, sending 123 to the parallel port (or reading from the input bits there) was a pain. The way to do it depended on what Delphi you used and what OS the program had to run under. No longer, hurrah!

Some time ago, a kind reader sent me an email saying. 'use inpout32.dll. It enables the sample programs in Jan Axelson's book Parallel Port Complete'. (Link okay since before 3/05). It offers help with: • Information and tools relating to parallel ports, • RS-232 and RS-485 serial communications, 8052-Basic, • Microcontrollers, and making printed-circuit boards.) It took me a while to get over my fear of DLLs, but am I glad I did!

They are no big deal. Used in moderation. Details are given in my. That is written for Delphi programmers, but C or VB (yuck) programmers will find help there, too. If you use inpout32.dll (freeware, dll and source code available from ), then one version of your program will run on many different operating systems. Win 3x to XP at last count, including NT.

(My software for XP relies on this dll.) ============= The page you are reading has been around for a while. Way back to MS-DOS days in fact. In February 2010, I moved (pre-NT) to its own page. ---- A newsgroup post said that in QuickBasic you do the following. This probably only works on pre-Win98 systems.

Out &h378,123 The &h378 is just another way of saying 888. The &H part says 'what follows is written in hexadecimal (aka 'hex'). Hex 378 is the same as decimal (our 'normal') 888.

It's like the 'difference' between '12', 'twelve' and 'dozen'. ---- For NT, XP, etc, if you don't want to use the better way (using inpout32.dll, ), you first need to install a port driver. Here are a few URLs you could explore: TVicHW32 DriverX Tinyport (NT only) (How to access the other lines of the parallel port is covered further down the page.) Next, a little 'side-bar', probably in the wrong place, but maybe you'll find fun: To control 8 lights from a parallel port or 8 pins of a is extremely easy. If you want to control more, you are going to have to design some external electronics with 'latches'.

Three lines from the parallel port will go to something like a 74138 which selects one line of 8 outputs from the 74138 according to the pattern of ons and offs on the three inputs to the 74138. You will also use one line of the parallel port to say 'latch now, data is valid', i.e., the signals you're seeing are the signals I want you to notice. This 'latch now' signal is how you avoid problems while the signals are changing. The remaining 4 lines from the parallel port will be data lines. Thus, you will be able to change the state of four lights at a time, but you will have 8 banks of four lights, so the circuit, potentially, could have 40 lights (or other output devices) on it.

Hardware Imagine you are looking at the back of your PC, and that the parallel port socket is horizontal, with the long row of socket on top. The numbers of the sockets at the ends of the rows are. 14 (See below for where things are to be found on the connector at the end of the cable normally plugged into a printer.) The 'interesting' pins are: Data bits 0-7: Pins 2 to 9, respectively. If you write to address 888 (decimal), you should see the outputs on those pins change. (The address is different in some circumstances, but try 888. In the 'good old days', you could simply use the following Borland's Delphi or Turbo Pascal: port[888]:=254 would set all bits but the first one high.) See for how you read and write to the correct places today.

The NUMBER you get, or write, hasn't changed. Pins 18-25: Signal ground. For a VERY simple experiment, connect an LED to pin2, a 680ohm resistor to the LED, and then the other end of the LED to pin 19.

If it doesn't work. Try turning the LED around!) Inputs: If you read address 889, you can discover the state of 5 pins. They determine the state of bits 3-7 of 889. BTmp:=port[889] was the old 'raw' Delphi or Pascal you needed. Obviously, you do clever things with the result of that. The bits are mapped and named as follows: Bit Pin Name 3 15 Error 4 13 Select In 5 12 Paper Empty 6 10 Acknowledge 7 11 Busy (A trap for the unwary.

'Busy' is inverted 'just inside' the computer. Thus if you apply a '1' to all of the pins, you'll see 01111xxx when you read 889! Isn't computing fun?) Before turning to more generally useful things, I might as well finish off the other pins. Write to 890 to set the state of the following pins: Bit Pin Name 0 1 Strobe 1 14 Auto Linefeed 2 16 Initialize 3 17 Select Out The rest of this page is rough. The layout is a mess (sorry), and there's more editing to do (you're welcome) but there's a lot of good info and links below and on the linked pages.
