.Sh EXAMPLES
To see the devices' current access modes, use the command line:
.Pp
.Dl atacontrol mode 0
.Pp
which results in the modes of the devices being displayed as a string
like this:
.Pp
.Dl Master = WDMA2
.Dl Slave = PIO4
.Pp
This means that ata0-master is in DMA mode,
ata0-slave is in PIO mode,
and so forth.
You can set the mode with atacontrol and a string like the above,
for example:
.Pp
.Dl atacontrol mode 0 PIO4 PIO4
.Pp
The new modes are set as soon as the atacontrol command returns.
