puc — PCI “Universal” Communications driver
device pci device puc device uart device ppc
This driver acts as a shim to connect PCI serial and parallel ports to the uart(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.
The PC Card attachment of this driver is scheduled for removal prior to the release of FreeBSD 13.0
This driver took the idea from the NetBSD puc driver.
