.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver provides support for PCI communications cards containing
|
|
|
|
|
simple communications ports, such as NS16550-family
|
|
|
|
|
.Pf ( Nm com )
|
|
|
|
|
serial ports and standard PC-like
|
|
|
|
|
.Pf ( Nm lpt )
|
|
|
|
|
parallel ports.
|
|
|
|
|
The driver is called
|
|
|
|
|
.Dq universal
|
|
|
|
|
because the interfaces to these devices aren't nearly as well
|
|
|
|
|
defined and standard as they should be.
|
|
|
|
|
.Pp
|
|
|
|

The driver currently supports the following cards:
|
|

.Pp
|
|
|
|
|
but support for them (and for similar cards) should be trivial to add.
|
|
|
|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Ar port
|
|
|
|
|
locator is used to identify the port (starting from 0) on the
|
|
|
|
|
communications card that a subdevice is supposed to attach to.
|
|
|
|
|
Typically, the numbering of ports is explained in a card's
|
|
|
|
|
hardware documentation, and the port numbers used by the driver
|
|
|
|
|
are the same as (or one off from, e.g. the manual uses ports
|
|
|
|
|
numbered starting from 1) those described in the documentation.

.Sh HISTORY
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver appeared in
|
|
|
|
|
.Nx 1.4 .
|
|
|
|
|
.Sh AUTHOR
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver was written by Chris Demetriou.
|
|
|
|
|
.Sh BUGS
|
|
|
|
|
The current design of this driver keeps any
|
|
|
|
|
.Nm com
|
|
|
|
|
ports on these cards from easily being used as console. Of
|
|
|
|
|
course, because boards with those are PCI boards, they also suffer
|
|
|
|
|
from dynamic address assignment, which also means that they
|
|
|
|
|
can't easily be used as console.
|
|
|
|
|
.Pp
|
|
|
|
|
Some of cards supported by this driver have jumper-selectable
|
|
|
|
|
.Nm com
|
|
|
|
|
port clock multipliers, which are unsupported by this
|
|
|
|
|
driver. Those can be easily accommodated with driver flags.
|
|
|
|
|
.Pp
|
|
|
|
|
Some ports use an
|
|
|
|
|
.Nm lpt
|
|
|
|
|
driver other than the machine-independent driver. Those ports
|
|
|
|
|
will not be able to use
|
|
|
|
|
.Nm lpt
|
|
|
|
|
ports attached to
|
|
|
|
|
.Nm
|
|
|
|
|
devices.
