the structure definitions come from NetBSD to make it easier to share card definitions. The driver only acts as a shim between the pci bus and the sio driver. Later pci parallel ports could also be supported through this driver. Support for most single and multiport pci serial cards should be as simple as adding its definition to pucdata.c Tested with the following pci cards: Moxa Industio CP-114, 4 port RS-232,RS-422/485 Syba Tech Ltd. PCI-4S2P-550-ECP, 4 port RS-232 + 2 parallel ports Netmos NM9835 PCI-2S-550, 2 port RS-232
