NAME
puc
- PCI
``universal''
communications card driver
SYNOPSIS
puc* at pci? dev ? function ?
com* at puc? port ?
lpt* at puc? port ?
DESCRIPTION
The
puc
driver provides support for PCI communications cards containing
simple communications ports, such as NS16550-family
(com)
serial ports and standard PC-like
(lpt)
parallel ports.
The driver is called
``universal''
because the interfaces to these devices aren't nearly as well
defined and standard as they should be.
The driver currently supports the following cards:
- Dolphin Peripherals 4014 (dual parallel)
-
- Dolphin Peripherals 4035 (dual serial)
-
- NetMos NM9835 (dual parallel and single serial)
-
- SIIG Cyber 2P1S PCI (dual parallel and single serial)
-
- SIIG Cyber 2S1P PCI (dual serial and single parallel)
-
- SIIG Cyber 4S PCI (quad serial)
-
- SIIG Cyber I/O PCI (single serial and single parallel)
-
- SIIG Cyber Parallel Dual PCI (dual parallel)
-
- SIIG Cyber Parallel PCI (single parallel)
-
- SIIG Cyber Serial Dual PCI (dual serial)
-
- SIIG Cyber Serial PCI (single serial)
-
- VScom PCI-200 (dual serial)
-
- VScom PCI-400 (4-port serial
-
- VScom PCI-800 (8-port serial)
-
- Titan PCI-800 (8-port serial)
-
- Titan PCI-200 (dual serial)
-
- NEC PK-UG-X001 K56flex PCI Modem
-
- NEC PK-UG-X008
-
- Lava Computers 2SP-PCI (single parallel)

-
- Actiontec 56K PCI Master
-
- Oxford Semiconductor OX16PCI952 (dual serial and single parallel)
-
- Oxford Semiconductor OX16PCI954 (4-port serial)
-
- NetMos 1P PCI (single parallel)

-
- Moxa Technologies SmartIO CP104/PCI (4-port serial)
-

The driver does not support the cards:
- Dolphin Peripherals 4006 (single parallel)
-
- Dolphin Peripherals 4025 (single serial)
-
- Dolphin Peripherals 4078 (dual serial and single parallel)
-
but support for them (and for similar cards) should be trivial to add.
The
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.

BUGS
The current design of this driver keeps any
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.
Some of the cards supported by this driver have jumper-selectable
com
port clock multipliers, which are unsupported by this
driver. Those can be easily accommodated with driver flags, or by
using a properly scaled baud rate when talking to the card.
Some of the cards supported by this driver, e.g. the VScom PCI-800,
have software-selectable
com
port clock multipliers, which are unsupported by this driver.
Those can be accommodated using internal driver flags, or by using
a properly scaled baud rate when talking to the card.
Some ports use an
lpt
driver other than the machine-independent driver. Those ports
will not be able to use
lpt
ports attached to
puc
devices.
