Hallo Oliver,
The Serial Peripheral Interface (SPI) circuit is a synchronous serial
data link that is standard across many Motorola microprocessors and other
peripheral chips. It provides support for a high bandwidth (1 megabaud)
network connection amongst CPUs and other devices supporting the SPI.
To implement this without special hardware on a PC, you'll have to "bit
bang" it. While this could be done using CTS, RTS and DTR on the PC, it
would require some level shifting hardware to convert to/from RS232 signal
levels.Really the parallel port would be much easier.
I'd consider writing a DLL in C and calling that. Better still, grab a
microcontroller with a built in full speed hardware supported SPI interface
as well as a UART, and stick that on the
serial port.
