Good day all.
I am looking for help and advice with regards to Printer Port Handshaking.
I have a duel printer port PCI card based on the Moschip Semiconductor MCS9865IV-AA Chip.
When the card is fitted and installed, windows see two new ECP printer ports.
Both ports work fine.
I need to be able to force one of the ports from ECP to SPP mode.
Reading the Datasheets for the MCS9865IV-AA, it says:
I am not using the printer ports for any standard devices, like printers, scanners, etc.
The printer ports are part of a CNC system, running Mach3 software, that uses the printer port inputs / outputs to control step and direction pulses.
ECP or EPP Mode is find for sending out step and direction pulses, but does not work for input signals, for that I need to use SPP mode.
So my question is: What is involved to make a SPP handshake signal to force the port from ECP to SPP mode?
Can it be done with simple hardware, or will I have to use a PicAxe or Arduino microcontroller?
Thanks for your time.
Best Regards.

But now is when things get more intresting.Parallel Port Features
Parallel port will support SPP/CBFIFO/ECP/EPP modes. Parallel port mode will be automatically configured to the required mode after handshaking with the connected device.
