NAMEctau - driver for synchronous Cronyx Tau WAN adapters
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
DESCRIPTIONThe sysctl Cm net.inet.tcp.syncookies 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 sysctl Cm net.inet.tcp.syncookies 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:
- 0x200, 0x220, 0x240, 0x260, 0x280, 0x2a0, 0x2c0, 0x2e0, 0x300, 0x320, 0x340, 0x360, 0x380, 0x3a0, 0x3c0, 0x3e0
- 3, 5, 7, 10, 11, 12, 15
- 5, 6, 7
The sysctl Cm net.inet.tcp.syncookies 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 sysctl Cm net.inet.tcp.syncookies adapter configuration.
HARDWAREThe sysctl Cm net.inet.tcp.syncookies 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)
