+.Sh NAME
+.Nm umcs
+.Nd USB support for serial adapters based on the MCS7820 and MCS7840 chips
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device umcs"
+.Ed
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+umcs_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for various multiport serial adapters based on the MosCom
+MCS7820 and MCS7840 chips. They are 2- or 4-port adapters with full-featured
+16550-compatible UARTs and very flexible baud generators. Also, these chips
+support RS422/RS485 and IrDA oprations.
+.Pp
+The device is accessed through the
+.Xr ucom 4
+driver which makes it behave like a
+.Xr tty 4 .
+.Pp
+Different ports on device are presented as sub-units, like
+.Pa /dev/ttyU0.1
+and
+.Pa /dev/ttyU0.2
+.Sh HARDWARE
+The
+.Nm
+driver was tested on the following adapters:
+.Pp
+.Bl -bullet -compact
+.It
+ST Lab U-360 two-port serial USB adapter
+.It
+ST Lab U-400 four-port serial USB adapter
+.El
+.Sh SEE ALSO
+.Xr tty 4 ,
+.Xr ucom 4 ,
+.Xr usb 4
+.Sh BUGS
+This driver doesn't support access to any fine tunes of
+chip, like RS522/RS485 mode, non-standard baudrates, etc.
+.Sh HISTORY
+The
+.Nm
+driver
+appeared in ports since December of 2010.
