Serial input via parallel port

Can someone please kindly explain how we can accept serial data as input from a parallel port using C #. Or serial communication through a parallel port.

I really wouldn't be transferring your data this way as you head into a world of pain. It is much better to use a USB serial IC like the excellent ones made by FTDI . In simple terms, your TTL data is transferred over USB. Thanks to the FTDI drivers, the data is displayed as a virtual serial port that your program can read in the usual way.

Hope it helps.

It is not clear from your question if you are looking for a software or hardware solution. An analog external serial converter (hardware) provides a simple solution.



If you're looking for a software-only solution, you want to do " bit banging ". Unfortunately, this requires precise timing, which can be extremely difficult in managed code. Such a program is typically embedded in a lower-level language such as assembly or C, where there is direct access to the hardware. Here is another article specifically for using the paralell port for serial communication.

It looks like you are doing something wrong. If you need a serial input, why not use a serial port? I believe the RS232 standard is widely supported. The parallel port is for parallel data transmission.
