.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 usb"
|
|
.Cd "device ucom"
|
|
.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 operations.
|
|
.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:

ST Lab U-360 two-port serial USB adapter
|
|

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver
|
|
appeared in ports since December of 2010.
|
|
.Sh AUTHORS
|

|
|
.Sh BUGS
|
|
This driver doesn't support access to any fine tunes of
|
|
chip, like RS522/RS485 mode, non-standard baudrates, etc.
