Dear davmarc,<br />
If I had SDK (or DDK?) documentation... I have seen Microsoft and Borland Help for DeviceIOControl recently but example doesn't explain what I need. In DOS IOCTL pointer to data is passing via DX:DS registers. Corresponding flat regs struct doesn't include these. Probably one should pass data via EDS:ESI? Or No?<br />
Frankly I meant that anybody did these thing recently and didn't yet forget the exact receipt. &nbsp;<br />
<br />
Thanks anyway.<br />
