- I am attempting to read and write data to the parallel.device in order
- to communicate with an interface I built. I know that the parallel port on
- my Amiga 1000 works. The interface is not yet connected as I am still writing
- the interface software in assembly.
-
- Here is my problem:
- I have successfully opened the parallel device and have managed to
- send it Read and Write commands through the IOExtPar structure. By using a
- program called TDebug, I have monitored the parallel.device and know that the
- commands are reaching the device. However, I do not seem to be transmitting or
- receiving any actual data through the parallel port. Is there anyone who can
- tell me what I am doing wrong? Do I have to access the hardware addresses to
- do this sort of thing?
-
- Anything helpful would be appreciated.
