Doh! It's been a while since I used these. I was slightly wrong; actually both the 232 and 245 devices can be accessed either via a serial port interface (COMx on windows, /dev/??? on linux etc.) or via a direct API. The 245 provides a parallel FIFO and the 232 a serial data link, so you'd wa

Soren, I don't know about the USB parallel port converters but there are variousways you can add USB connectivity yourself. A simple way are the USB devices from FTDI (http://www.ftdichip.com/FTProducts.htm) Either the FT232R or the FT245R. These are both single chip solutions that

Hi, I want to control some motors using the parallel port.. however, my laptop does not have any parallel ports (very few do). What I do have is a USB->Parallel converter... I thought about using PyParallel, but the USB->Parallel converterdoesn't actually map to the LPT port .. and PyParallel
