SPIF(4) NetBSD Kernel Interfaces Manual SPIF(4) NAME spif -- SBus (spiffy) Serial/Parallel Interface SYNOPSIS spif* at sbus? slot ? offset ? (sun4c/sun4m) stty* at spif? (sun4c/sun4m) sbpp* at spif? (sun4c/sun4m) DESCRIPTION The spif driver provides support for the Sun Serial/Parallel Interface card (Sun part number 501-1931) based around the Cirrus Logic CD180 octal serial controller and the Cirrus Logic PPC2 parallel port controller. The device minor numbers for this driver are encoded as follows: +---+---+---+---+---+---+---+---+ | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | +---+---+---+---+---+---+---+---+ | | | | | | | | | | | | | +---+---+---> port number | | | | | | | | | +---------------> unused | | | | | | | +-------------------> dial-out (on tty ports) | | | | | +-----------------------> unused | | +---+---------------------------> card number Up to four cards are supported in the system. Each of the serial ports has an 8 byte FIFO for receive and transmit as well as automatic hardware (RTS/CTS) flow control. FILES /dev/tty[jkl][0-7] Serial ports /dev/sbpp[0-3] Parallel ports DIAGNOSTICS spif%d: ccr timeout A timeout occurred while writing to one of the CD180 registers. stty%d-%d: ring overflow Incoming characters were discarded because the application in control of the device did not read the input fast enough. SEE ALSO intro(4), sbus(4), tty(4) HISTORY The spif driver was first supported in OpenBSD 2.5. AUTHORS The driver was written by Jason Wright <jason@thought.net>, and is heav- ily based on the magma(4) driver written by Iain Hibbert. TODO The parallel port is not supported yet. Dial-out (cua) devices are not yet supported. NetBSD 5.1 February 4, 1999 NetBSD 5.1
