controllers typically have multiple channels and support a number of serial communications protocols. The scc(4) driver is itself an umbrella driver that delegates the control over each channel and mode to a subordinate driver (like uart(4)). The scc(4) driver supports the Siemens SAB 82532 and the Zilog Z8530 and replaces puc(4) for these devices.

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
device driver provides support for various classes of SCCs.
|
|
It is an umbrella driver that delegates control of each independent
|
|
communication channel to subordinate drivers.
|
|
These subordinate drivers, like
|
|
.Xr uart 4 ,
|
|
take care of the details of the communication itself.
