.Dd July 11, 1998 .Dt PUC 4 .Os .Sh NAME .Nm puc .Nd PCI .Dq universal communications card driver .Sh SYNOPSIS .Cd "puc* at pci? .Cd "pccom* 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
f ( Nm com ) serial ports and standard PC-like
f ( 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.
p The driver currently supports the following cards:
p l -tag -width -offset indent -compact t Tn "Dolphin Peripherals 4014 (dual parallel)" t Tn "Dolphin Peripherals 4035 (dual serial)" t Tn "SIIG Cyber 2P1S PCI (dual parallel and single serial)" t Tn "SIIG Cyber 2S1P PCI (dual serial and single parallel)" t Tn "SIIG Cyber 4S PCI (quad serial)" t Tn "SIIG Cyber I/O PCI (single serial and single parallel)" t Tn "SIIG Cyber Parallel Dual PCI (dual parallel)" t Tn "SIIG Cyber Parallel PCI (single parallel)" t Tn "SIIG Cyber Serial Dual PCI (dual serial)" t Tn "SIIG Cyber Serial PCI (single serial)" t Tn "VScom PCI-800 (8 port serial, probably OEM)" t Tn "AT&T/Lucent Venus Modem (found on IBM 33L4618 card, Actiontec 56K, and others)" t Tn "US Robotics 3CP5609 PCI (modem)" t Tn "Lava Computers 2SP-PCI (parallel port)" t Tn "Lava Computers 2SP-PCI and Quattro-PCI (dual serial)" t Tn "NEC PK-UG-X008 (serial)" t Tn "NEC PK-UG-X001 K56flex PCI (modem)" t Tn "Koutech IOFLEX-2S (dual serial)" .El
p The driver does not support these cards:
p l -tag -width -offset indent -compact t Tn "Dolphin Peripherals 4006 (single parallel)" t Tn "Dolphin Peripherals 4025 (single serial)" t Tn "Dolphin Peripherals 4078 (dual serial and single parallel)" .El
p but support for them (and for similar cards) should be trivial to add.
p 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 SEE ALSO .Xr com 4 , .Xr lpt 4 , .Xr pci 4 .Sh HISTORY The .Nm driver first appeared in .Nx 1.4 . .Ox support was added in .Ox 2.7 . .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.
p 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, or by using a properly scaled baud rate when talking to the card.
p Some of the cards supported by this driver, e.g., the VScom PCI-800, have software-selectable .Nm com port clock multipliers, which are unsupported by this driver. Those can be accomodated using internal driver flags, or by using a properly scaled baud rate when talking to the card.
p 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.
