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