PUC(4) BSD Kernel Interfaces Manual PUC(4)NAME
puc -- PCI ``Universal'' Communications driver
SYNOPSIS
device pci
device puc
device sio
device ppc
DESCRIPTION
This driver acts as a shim to connect PCI serial and parallel ports to the sio(4) and ppc(4) driver.
The list of supported devices is in sys/dev/puc/pucdata.c. Support for new cards should be added there.
SEE ALSO ppc(4), sio(4)HISTORY
This driver took the idea from the NetBSD puc(4) driver and still uses the same structure to describe cards, to ease exchanging card info.
BUGS
Only serial ports are supported through the sio(4) driver at the moment.

atppc* at ofisa?
atppc* at pnpbios? index ?

options ATPPC_DEBUG
DESCRIPTION
atppc supports parallel ports and provides the low level support needed by higher level drivers such as ppbus(4). This driver attaches where
the traditional NetBSD lpt(4) driver would ordinarily. It provides the data transport and chip set manipulation needed by higher driver lay-
ers, such as ppbus(4) and lpt(4). This driver is designed to be one of many possible implementations supporting machine independent parallel
device support via ppbus(4).
IEEE 1284 support
atppc is intended to provide to data-link like services to higher level IEEE 1284 device drivers (such as ppbus(4)). atppc does not directly
support IEEE 1284 features such as mode negotiation but rather provides the necessary infrastructure to allow a higher level driver to pro-
vide these services.
atppc does provide chip set manipulation, device handshakes (where appropriate), low-level error detection, and data transfer.
Supported data transfer modes
atppc supports the following data transfer modes: Centronics Compatible (Standard), Nibble, Byte (PS2), Fast Centronics, ECP, and EPP. Stan-
dard and Fast Centronics modes are write only, Nibble and Byte modes are read only, and ECP and EPP modes are bidirectional.

The atppc driver is based on the ppc driver, which originally appeared in FreeBSD. The driver was ported over in NetBSD 2.0.
AUTHORS
This manual page is based on the FreeBSD ppc manual page. The information has been updated for the NetBSD port by Gary Thorpe.
BUGS
The FreeBSD driver includes support for some specific chip sets, specifically detection of some non-standard device I/O locations on the ISA
bus. This support was not ported over to the NetBSD version of the driver yet.
