So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...

???<BR><BR>I have a propriatery RS232 device that I need to connect to a computer that has no serial ports (newer laptop). The hardware has a dongle incorporated into the cable to unlock the software ...

This application note presents the process of converting a serial output into parallel output using common serial-to-parallel register integrated circuits. The document also discussed the CS556x/7x/8x ...

This converter may help if just the serial port on a personal computer is free, whereas the printer needs a parallel (Centronics) port. It converts a serial 2400 baud signal into a parallel signal.

The circuit shown in Figure 1 provides a simple, low-power means of digitizing analog signals and sending the data directly to a PC's serial port where it can easily be read, analyzed, and stored. The ...

For portable-sensing and data- acquisition applications, a laptop computer and its parallel port (LPT) make good bedfellows. Yet in the effort to extend battery life, many microprocessors and entire ...
