I was hoping that the ST printer port was bidirectional, but I have seen no documentation for it. The ST manual shows only one set of data pins on the printer socket, and the developer's kit only talks about writing to the printer, not reading from it. So: What are the pins on the printer socket for doing input to the ST? What does the software interface look like? Is it the obvious thing (using one of the BIOS input routines with the the printer device)? Dan Franklin

That means the same pins used for output are used for input. The software interface is the BIOS input routines with device parameters as you suspected.
