66.Pp
67A pair of two adapters can be united together by the special
68short inter-board cable. Two united adapters use the same
69IRQ and DMA channels and from the point of driver works
70as the single 16-channel multiplexer. One of the united
71boards is ``master'' and the other is ``slave''.
72.Pp
73The channels of the slave united board are numbered by the driver
74beginning with 8, for example, the united adapter of the model 100/500
75has channels 0, 8, 12, 13, 14, 15.
76.Pp
77The channels which have the RS-232 interface can be used
78both in synchronous and asynchronous modes (software selectable
79by cxconfig utility) and hence are called ``universal'' channels.
80.Sh "Asynchronous driver"
81The asynchronous channel device files have the names:
82.Pa /dev/ttyx#
83- for adapter cx0,
84.Pa /dev/ttyy#
85- for adapter cx1,
86.Pa /dev/ttyz#
87- for cx2.
88Here # is the channel number in hexadecimal form, 0-9-a-f.
89.Pp
90The driver fulfills the following standard ioctl requests (see
91.Xr ioctl 2 ) :

111.It TIOCMSET

151.Sh "Synchronous driver"
152The synchronous channels and universal channels, turned to the synchronous
153mode by the
154.Xr cxconfig 8
155utility, are accessible as network
156interfaces named ``cx#'' where # is the channel number, 0..47.
157All standard network interface parameters could be set by
158.Xr ifconfig 8
159utility.
| |
160The
| 68The
|
161.Xr cxconfig 8
162command is used to change some extended channel
163options, and also for setting the high-level software protocol
164(e.g. PpP or Cisco HDLC).
| 69.Nm
70driver supports autodetection.
71As for all non-PNP hardware using of
72autodetection could lead to some potential problems with other devices during
73detection of hardware.
74It is alway better to specify hardware resources manualy.
|
165.Pp
| 75.Pp
|
166The universal channels could be used both in asynchronous and synchronous modes.
167By default the asynchronous mode is set.
168The mode could be changed by
169.Xr cxconfig 8
170utility.
171The mode is blocked while the channel is busy (an asynchronous channel
172in open state or the network interface is up).
173.Sh "Synchronous Point-to-Point protocol"
174The Cronyx-Sigma driver uses the built-in implementation of the synchronous
175Point-to-Point protocol (sppp). It includes the support for such
176protocols as PpP/HDLC and Cisco/HDLC, and also the automatic
177connection loss test (via keepalive packets).
178The sppp protocol set is implemented as an independent module
179and could be used by other drivers of synchronous serial channels.
180The version of the driver for BSD/386 (BSDI) operating system
181also supports the usage of the general set of synchronous
182protocols, implemented inside the OS.
183The external protocol set could be selected by ``cxconfig ext'' command
184(see
185.Xr cxconfig 8 ) .
186.Sh "Channel Options Management"
187The
188.Xr cxconfig 8
189utility is used for setting the channels options.
190The channel options are generally set at the start of the operating
191system (for example, from the file
192.Pa /etc/rc ) .
193Note, that not all options have a sense for every particular
194case, and an attempt to set some of them can hang up the channel or
195the whole adapter.
196.Pp
197The actual channel options control functions are implemented via
198the ioctl-s on the special device file /dev/cronyx.
199There are the following ioctl-s available:
200.Pp
201.Bl -tag -width CXIOCXXXXXXX -compact
202.It CXIOCGETMODE
203Get the channel option values.
204.It CXIOCSETMODE
205Set the channel option values.
206.El
207.Pp
208The data argument of the ioctl call has an address of the options structure:
209.Bd -literal
210typedef struct {
211 unsigned char board; /* adapter number, 0..2 */
212 unsigned char channel; /* channel number, 0..15 */
