     ctau — driver for synchronous Cronyx Tau WAN adapters

     device ctau

     Additional options:
     device sppp
     options NETGRAPH
     options NETGRAPH_CRONYX

     In /boot/device.hints:

     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.

     The ctau driver supports the following cards:

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

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

     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/.
