.Sh NAME
.Nm puc
.Nd PCI
.Dq universal
communications card driver
.Sh SYNOPSIS
.Cd "puc* at pci? dev ? function ?"
.Cd "com* at puc? port ?"
.Cd "lpt* at puc? port ?"
.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
.Bl -tag -width -offset indent -compact
.It Tn "Dolphin 4014 (dual parallel)"
.It Tn "Dolphin 4035 (dual serial)"
.It Tn "SIIG CyberSerial PCI (single serial)"
.El
.Pp
The driver does not support the cards:
.Pp
.Bl -tag -width -offset indent -compact
.It Tn "Dolphin 4006 (single parallel)"
.It Tn "Dolphin 4025 (single serial)"
.It Tn "Dolphin 4078 (dual serial and single parallel)"
.It Tn "SIIG CyberParallel PCI (single parallel)"
.It Tn "SIIG CyberParallel Dual PCI (dual parallel)"
.It Tn "SIIG Cyber 2S1P PCI (dual serial and single parallel)"
.El
.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.
