On the PCI-6503 card with the 8255, I wan't one port use as input and
one port as output. To read from the port, I use the "Port Read" VI
(from the advanced section - not the "Dig Line" or the "Dig Port"
(from the Easy DIO) nor the "DIO Read"). But when ever this VI is
called, all the ports from the 8255 are resetet.
Wich VI do I have to use, that this does not happen ? Or is there no
other way, then first read the port an then write the other port from
a softcopy again (whould surprise me, if I had to do it this way).
