Way back in the day, analog/digital converters (ADCs) had simple, parallel interfaces, either TTL or high-level CMOS. Many of these converters could be clocked down to zero samples/second: once you ...

The MCS9901CV single-lane PCI Express (PCIe) to peripheral controller supports serial, parallel, ISA, and USB interfaces. It can provide 21 combinations of serial, parallel, USB, and ISA interfaces ...

The OXmPCI954 is designed to handle 15-Mbit/s asynchronous and 60-Mbit/s synchronous serial data rates. It integrates four high-performance UART channels, a 3.3-V PCI interface, and a local ...

Everyone knows that the world is analog in nature, yet we insist on dealing with analog signals by digital means. Analog sensor outputs are quickly converted to digital form to improve noise immunity ...

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 ...
