I have an old ISA output board that I built some years ago with 8 relays on board which are controlled from QBasic by:

OUT (hex address), (hex data)

the data parameter selects which combination of relays are switched on/off.

I am trying to figure out how to achieve the same effect in VB6 and suspect it may involve some API calls which I have managed before. Does any kind soul have the time to pont me in the right direction?
