Hi,

I have ideal to make rs232 to 4 parallel ports. each port have 8 bits signal. for cnc machine controler. On board can set out or input by dip jumper. Software just @A,0..127 mean you out port A with 0000 0000 .. FFFF FFFF bits and if we jump port D as input port then we send "@D". Port D will send bits status to PC via serial port. So will it be link board?

Regards,

Hello

I'm sorry but I don't understand what you want tout do.

Can you explain it ? Do you try to build and program this ?

Hi Jerome,

Yes, I will make the board. The new PC main boards have no printer port and serial port on board. It can help?
