NOTES¶

Historically, the driver for the Cronyx Tau WAN adapters was “ct”. This device name was changed to “ctau” to avoid conflicts with this pc98 ct driver. The network device name for ctau(4) is “ct”. Please see ctau(4) for the details for that device.

HISTORY¶

The ct device driver has been developed for NetBSD/pc98 and ported for FreeBSD. It first appeared in FreeBSD 4.4.

AUTHORS¶

The ct driver was written by Naofumi HONDA.
