# puc(4freebsd)

PCI “Universal” Communications driver

## NAME

**puc** – PCI “Universal” Communications driver

## SYNOPSIS

**device pci** **device puc** **device uart** **device ppc**

## DESCRIPTION

This driver acts as a shim to connect PCI serial and parallel ports to the [uart(4)](/uart/4.md) and [ppc(4)](/ppc/4.md) driver.

The list of supported devices is in *sys/dev/puc/pucdata.c*. Support for new cards should be added there.

## DEPRECATION NOTICE

The PC Card attachment of this driver is scheduled for removal prior to the release of FreeBSD 13.0

## SEE ALSO

[ppc(4)](/ppc/4.md), [uart(4)](/uart/4.md)
