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)

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
