Input and output for each line may set to one of following baud rates;

of 115200.
.Pp
If

is specified, the
.Nm
driver will not set the MCR_IENABLE bit on the UART. This is mainly for
use on AST multiport boards, where the MCR_IENABLE bit is used to control
whether or not the devices use a shared interrupt.

The
