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)

HISTORY¶
The
ctau
driver was added in
FreeBSD 5.3 and
FreeBSD 4.10.

driver for previous versions of
FreeBSD is available from
