127.Sh NOTES
128Historically, the driver for the Cronyx Tau WAN adapters was
129.Dq ct .
130This device name was changed to
131.Dq ctau
132to avoid conflicts
133with this pc98
134.Nm
135driver.
136The network device name for
137.Xr ctau 4
138is
139.Dq Li ct .
140Please see
141.Xr ctau 4
142for the details for that device.
143.Sh HISTORY
144The
145.Nm
146device driver has been developed for
147.Nx Ns /pc98
148and ported for
149.Fx .
150It first appeared in
151.Fx 4.4 .
