Hi all. I've been bravely trying to guess how the Alaris parallel port webcam is working, and I wanted to do some testing. After a study of Parport documents, I have written a small proggie that reads from the ECP port fine, and even get the manufacturers and other data from the cam.
I do not seem to find anywhere how to use the parport calls to send (or receive for that matter) Commands on the ECP bus. I am guessing all transactions are done in Forward (or Reverse) Data Mode. Does anyone know how to generate Commands (Fwd and Rev)? Short of writing manually to the base + 0xA00 addresses? Thanks, John
