NAME

     ct -- WD33C93[ABC] based CBUS SCSI host adapter driver

SYNOPSIS

     device ct
     device scbus

     In /boot/device.hints:

     For most PC-9801-55, -92 and compatibles:
     hint.ct.0.at="isa"

     For ELECOM bus-master SCSI adapters:
     hint.ct.0.at="isa"
     hint.ct.0.flags="0x30000"

     For I-O DATA SC98 adapters:
     hint.ct.0.at="isa"
     hint.ct.0.flags="0x10000"

     For LOGITEC adapters:
     hint.ct.0.at="isa"
     hint.ct.0.flags="0x50000"

     For TEXA adapters:
     hint.ct.0.at="isa"
     hint.ct.0.flags="0x20000"

     For adapters with SMIT transfer mode to enable SMIT transfer:
     hint.ct.0.at="isa"
     hint.ct.0.flags="0x40000"
     hint.ct.0.maddr="0xdc000"

     Flags meaning:
	   0x00000   DMA transfer mode for an NEC PC-9801-55, -92 (or compatibles), ICM IF-2660, Midori-Denshi MDC-554NA, or Logitec LHA-N151
	   0x10000   DMA transfer mode for an I-O DATA SC-98II
	   0x20000   bus-master transfer mode for a TEXA HA-55BS2, its successors, or Midori-Denshi MDC-926R
	   0x30000   bus-master transfer mode for an ELECOM bus-master SCSI adapter
	   0x40000   SMIT transfer mode (for supported adapters only)
	   0x50000   bus-master transfer mode for a Logitec LHA-20x series, ICM IF-2766, IF-2766ET, IF-2767 or IF-2769

DESCRIPTION

     The ct driver provides access to the SCSI bus connected to a WD33C93[ABC] based host adapter.

HARDWARE

     The ct driver supports the following adapters:

     o	 ELECOM bus-master SCSI adapters
     o	 I-O DATA SC-98II
     o	 ICM IF-2660, IF-2766, IF-2766ET, IF-2767 and IF-2769
     o	 Logitec LHA-N151 and LHA-20x series
     o	 Midori-Denshi MDC-554NA and MDC-926R
     o	 NEC PC-9801-55, 92 and compatibles
     o	 SMIT transfer type SCSI host adapters
     o	 TEXA HA-55BS2 and its later models

NOTES

     Historically, the driver for the Cronyx Tau WAN adapters was ``ct''.  This device name was changed to ``ctau'' to avoid conflicts with this
     pc98 ct driver.  The network device name for ctau(4) is ``ct''.  Please see ctau(4) for the details for that device.

HISTORY

     The ct device driver has been developed for NetBSD/pc98 and ported for FreeBSD.  It first appeared in FreeBSD 4.4.

AUTHORS

     The ct driver was written by Naofumi HONDA.

NAME

     ctau -- driver for synchronous Cronyx Tau WAN adapters

SYNOPSIS

     device ctau

     Additional options:
     device sppp
     options NETGRAPH
     options NETGRAPH_CRONYX

     In /boot/device.hints:
     hint.ctau.0.at="isa"
     hint.ctau.0.port="0x240"
     hint.ctau.0.irq="15"
     hint.ctau.0.drq="7"

DESCRIPTION

     The ctau driver needs either sppp(4) or netgraph(4).  Which one to use is determined by the NETGRAPH_CRONYX option.  If this option is
     present in your kernel configuration file, the ctau driver will be compiled with netgraph(4) support.  Otherwise, it will be compiled with
     sppp(4) support.

     The base I/O port address specified in /boot/device.hints must match the port address set by the jumpers on the board.  The DMA I/O channel
     and interrupt request numbers are configured by software at adapter initialization.  Legal values are:

     Port:  0x200, 0x220, 0x240, 0x260, 0x280, 0x2a0, 0x2c0, 0x2e0, 0x300, 0x320, 0x340, 0x360, 0x380, 0x3a0, 0x3c0, 0x3e0
     IRQ:   3, 5, 7, 10, 11, 12, 15
     DMA:   5, 6, 7

     The ctau driver supports autodetection.  As for all non-PNP hardware, using autodetection could lead to some potential problems with other
     devices during the hardware detection process.  It is always better to specify hardware resources manually.

     Refer to sconfig(8) for information about the ctau adapter configuration.

HARDWARE

     The ctau driver supports the following cards:

     o	 Cronyx Tau (RS-232/V.35)
     o	 Cronyx Tau/R (RS-530/RS-449)
     o	 Cronyx Tau/E1 (fractional E1)
     o	 Cronyx Tau/G703 (unframed E1)

SEE ALSO

     cp(4), cx(4), sppp(4), ifconfig(8), sconfig(8), spppcontrol(8)

HISTORY

     The ctau driver was added in FreeBSD 5.3 and FreeBSD 4.10.  The ctau driver for previous versions of FreeBSD is available from
     http://www.cronyx.ru/.
