Getting data to a storage medium requires transmission. Parallel transmission has historically been the preferred way to write data to disk. But at current speeds, serial transmission can be faster ...

Traditionally, external SRAMs feature a parallel interface. Given the memory requirements for most of SRAM-based applications, it’s no surprise that parallel is a better option. For the high ...

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 ...
