|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports serial adapters based on the
|
|
XR21V1410, XR21V1412, and XR21V1414 chipsets.
|
|
Devices range from single port to eight port (implemented as a
|
|
USB hub and two
|
|
.Nm
|
|
four port instances behind it).
|
|
Examples of hardware known to work with this driver are:

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver attaches the Exar XR21V141x multiport chipset with individual
|
|
port drivers via
|
|
.Xr ucom 4 ,
|
|
which makes it behave like a
|
|
.Xr tty 4 .

.Sh HISTORY
|
|
The

The multi-port
|
|
.Nx
|
|
driver is based on the
