36 .Nd USB support for serial adapters based on the MCS7820 and MCS7840 chips
38 To compile this driver into the kernel,
39 place the following lines in your
40 kernel configuration file:
41 .Bd -ragged -offset indent
47 Alternatively, to load the driver as a
48 module at boot time, place the following line in
50 .Bd -literal -offset indent
56 driver provides support for various multiport serial adapters based on the MosCom
57 MCS7820 and MCS7840 chips.
58 They are 2- or 4-port adapters with full-featured
59 16550-compatible UARTs and very flexible baud generators.
61 support RS422/RS485 and IrDA operations.
63 The device is accessed through the
65 driver which makes it behave like a
68 Different ports on device are presented as sub-units, like
75 driver was tested on the following adapters:
79 ST Lab U-360 two-port serial USB adapter
81 ST Lab U-400 four-port serial USB adapter
91 appeared in ports since December of 2010.

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