+.Op Ar device name
+.Op Ar data rate options
+.Op Ar protocol options ...
+.Op Ar interface options ...
+.Sh DESCRIPTION
+The
+.Nm
+utility is used for configuring the channel options of the Cronyx
+adapters. In asynchronous mode all the parameters should be set by standard
+.Xr stty 1
+utility, with
+.Nm
+you could set only few of them (see below).
+.Pp
+Some of the options could be set only on free channels, that is the
+corresponding network interface in 
+.Ar down
+state in the synchronous mode, and in the asynchronous mode the asynchronous
+terminal device
+.Pa /dev/tty*
+closed.
+.Pp
+Other channel options could be changed
+.Do on the fly
+.Dc .
+Generally, the channel options are set up during the operating system startup,
+for example from the
+.Pa /etc/rc
+file.
+.Pp
+Note, that not all options have a sense for every particular
+case, and an attempt to set some of them can hang up the channel or
+the whole adapter.
+.\"--------------------------------------------------------------
+.Ss "Information options"
+You can specify only one of these options. If information option is specified,
+sconfig will show corresponding information and will ignore all other options,
+except
+.Ar device name.
+See also description of the 
+.Ar device name.
+.Bl -tag -width 10n
+.It <none>
+This will show settings of the channel.
+.It Fl a
+Print all settings of the channel.
+.It Fl i
+Print interface settings, equal to the output of
+.Xr ifconfig 1
+command.
+.It Fl m
+Print modem signal status. The description of all signals can be found in
+any document related to the modems. Only LE signal should be described. If
+this signal is On, than some what use channel. If it is Off, than channel is
+free.
+.It Fl s
+Print brief channel statistics. This is general statistics. See also
+.Fl x

+.Fl f
+,
+.Fl t
+and
+.Fl u
+options. For the description of output, see below.
+.Pp
+This statistics is very useful if something goes wrong. For example, if you

+statistics accumulated for period of time equal to 15 minutes. For the
+description of output, see below.
+.It Fl f
+Print full E1/G703 statistics. This option shows all E1/G703 statistics that
+shows previous option(
+.Fl e
+), but also total statistics for whole period of time and statistics for 24
+hours (if available). For the description of output, see below.
+.It Fl t

+.\"--------------------------------------------------------------
+.Ss "Device selection"
+Device is equal to the name of the interface that is used for a name of
+the interface that is sees
+.Nm ifconfig.
+The channel number depends on the order of loading drivers by the system.
+Some times people confuse channel number and adapter number because of the
+same spelling. Adapter number appears in kernel context, channel number
+in configuration context.
+.Bl -tag -width 10n
+.It <none>
+You can omit device name only if you want to get information. This will cause
+printing information about all available channels of Cronyx adapters. In the
+case you want to make some settings you MUST specify device name.
+.It cx##
+This is the channel name for the Sigma family of Cronyx adapters. (ISA bus)
+.It ct##
+This is the channel name for the Tau family of Cronyx adapters. (ISA bus)
+.It cp##
+This is the channel name for the Tau-PCI family of Cronyx adapters. (PCI bus)
+.It ce##
+This is the channel name for the Tau32-PCI family of Cronyx adapters. (PCI bus)
+.El
+.\"--------------------------------------------------------------
+.Ss "Data rate options"
+.Bl -tag -width 10n
+.It value
+If case of nonzero value it will cause setting data rate to given value and
+setting the internal clock source of the synchronization (in synchronous mode).
+Zero value is equal to the
+.Ar extclock.
+The transmitted data (TXD) are synchronized using the internal on-board timing
+generator, the internally generated timing signal is driven on the TXCOUT pin,
+and the signal on the TXCIN pin is ignored. This mode is used for direct
+terminal-to-terminal communication, e.g. for connecting two computers together
+in a synchronous mode via relatively short cable.  This method should also be
+used for testing channels with an external loopback connector.
+.It extclock
+Set the external timing clock source of synchronous channels. External clock
+mode is the most common method for connecting external modem hardware. In this
+mode the external timing signal is received on TXCIN pin of the connector,
+and it is used as a synchronization clock for transmitting data (TXD).
+.El
+.\"--------------------------------------------------------------
+.Ss "Protocol options"
+Note. These option could be set only if channel is free and they requires
+specifying of the device name.
+.Bl -tag -width 10n
+.It async
+Set asynchronous protocol (or mode). In this mode Cronyx adapters behave as a
+usual serial devices and you may work with them using usual serial utilities.
+All asynchronous settings are performed via serial configuration utilities. With
+.Nm sconfig
+you may set only a few of them. See also
+.Xr stty 1 .
+(Only for Sigma family)
+.It cisco
+Set the Cisco HDLC synchronous protocol.
+.It fr
+Set the Frame Relay synchronous protocol (ANSI T1.617 Annex D).
+.It ppp
+Set the PPP synchronous protocol. Parameters to the PPP could be set by the
+command
+.Xr spppcontrol 1 .
+.It keepalive=on, keepalive=off
+Turns on/off sending keepalive messages. This option is used only for
+synchronous PPP. If this option is on, than PPP will periodically send
+echo-request messages. If it would not receive any echo-reply messages for
+some (definite) period of time it will break connection. It is used for
+tracking line state.
+.It idle
+You are using NETGRAPH. Protocol depends on connected module.
+.El
+.\"--------------------------------------------------------------
+.Ss "Interface options"
+Not all of these options could be set on running channel and not all of them
+are suits to all kind of adapters/channels. In all dual state options off is
+default value. All this options is not applicable in asynchronous mode, except
+debug option.
+.Bl -tag -width 10n
+.It port=rs232, port=v35, port=rs449
+Set port type for old Sigma models. 
+.It cfg=A, cfg=B, cfg=C
+Set configuration for the adapter. This option could be set only for Tau/E1
+and Tau/G703 and only if all channels are not running.
+.Ar cfg=A
+- Two independent E1/G703 channels. This is default setting.
+.Ar cfg=B (Only for ISA models)
+- For Tau/G703 this mean one G703 channel and one digital channel.
+For Tau/E1 first physical channel divides on to subchannels. One of them
+goes to the first logical channel and another one goes to the second physical
+channel. Second (logical) channel is digital channel.
+.Ar cfg=C
+- This configuration is used only for E1 models. In this case first
+physical channel consists of three data flows. Two of them go to two
+(logical) channels. The last one goes to the second physical channel. On new
+models (Tau32-PCI, Tau-PCI/2E1 and Tau-PCI/4E1) this configuration means single source
+of synchronization and passing all unused (in both channels) timeslots from
+one channel to other. For the detailed description of the configuration see
+your documentation to the adapter. This option could not be set on running
+channel.
+.It loop=on, loop=off
+Turn on/off internal loopback. This mode is useful for testing. Switch on this
+option and try to send something. If you have no any interrupt, than, probably,
+you forgot to switch using IRQ for PCI to ISA bus. Check your BIOS settings.
+.It rloop=on, rloop=off (Only for Tau32-PCI and Tau-PCI/E3)
+Turn on/off remote loopback. This mode is also useful for testing.
+.It dpll=on, dpll=off
+Turn on/off digital phase locked loop mode (DPLL). When enabled, the receiver
+timing clock signal is derived from the received data. Must be used with NRZI
+encoding, to avoid the synchronization loss.
+.It nrzi=on, nrzi=off
+Turn on/off nrzi encoding. In off state nrz encoding is used. NRZ - the zero
+bit is transmitted by the zero signal level, the one bit - by the positive
+signal level. NRZI - the bit number zero is transmitted by the change of the
+signal level, the one bit - by the constant signal level. Commonly is used with
+dpll=on option.
+.It invclk=on, invclk=off
+Invert the both transmit and receive clock signals (Tau and Tau-PCI only).
+.It invrclk=on, invrclk=off
+Invert the receive clock signals (Tau-PCI only).
+.It invtclk=on, invtclk=off
+Invert the transmit clock signals (Tau-PCI only).
+.It higain=on, higain=off
+Turn on/off increasing the E1 receiver non linear sensitivity to -30 dB (E1
+only). In of state the sensitivity is -12 dB. This allows increasing line
+distance.
+.It cablen=on, cablen=off (Only for Tau-PCI/T3 and Tau-PCI/STS-1)
+Turn on/off adjusting transmit signal for long cable T3/STS-1.
+.It monitor=on, monitor=off
+Turn on/off increasing the E1 receiver lines sensitivity to -30 dB
+(Tau32-PCI, Tau-PCI/2E1 and Tau-PCI/4E1 only). This could be used for interception
+purposes.
+.It phony=on, phony=off
+Turn on/off the so-called phony mode (Tau32-PCI and Tau-PCI E1 family only). This mode allows
+receiving raw CEPT frames from E1 line. Raw frames could be accessed, for
+example, via raw protocol. Packets would come at rate of 500 frames per second
+with length 16xN (for Tau-PCI/E1 model), where N is the number of timeslots. For
+Tau-PCI/2E1 and Tau-PCI/4E1 N should be equal to 32 independently from number of
+used timeslots.
+.It unfram=on, unfram=off
+Turn on/off unframed mode (Tau32-PCI, Tau-PCI/2E1 and Tau-PCI/4E1 only).
+.Ar unfram=on
+switches channel to unframed G.703 mode.
+.Ar unfram=off
+switches channel to framed E1 (G.704 mode). 
+.It scrambler=on, scrambler=off
+Turn on/off the scrambling of G.703 data (Tau32-PCI, Tau-PCI/G.703 and Tau-PCI/2E1,
+Tau-PCI/4E1 in unframed mode only).
+.It use16=on, use16=off
+Turn on/off the usage of 16-th timeslot for data transmission (Tau32-PCI and Tau-PCI E1 family only).
+Normally 16-th timeslot is used for signaling information (multiframing CAS).
+.It crc4=on, crc4=off
+Turn on/off CRC4 superframe mode (E1 only). 
+.It syn=int, syn=rcv, syn=rcv0, syn=rcv1, syn=rcv2, sync=rcv3
+.Ar int
+- use an internal clock generator for G703 transmitter
+(clock master). 
+.Ar rcv
+- use the G703 receiver data clock as the transmit clock
+(clock slave). 
+.Ar rcv0, rcv1, rcv2, rcv3
+- use the G703 receiver clock of the other channel
+(E1 models only). 
+.It dir=<number>
+Binds logical channel to the physical channel (Tau32-PCI, Tau-PCI/2E1 and Tau-PCI/4E1
+only). Using this parameter you could, for example, split E1 physical channel
+into several channels.
+.It ts=interval
+Set up the list of timeslots to use by the channel (E1 only). The
+timeslots are numbered from 1 to 31, and are separated by comma or minus sign,
+giving an interval. For example: "ts=1-3,5,17". 
+.It pass=interval
+Set up the list of timeslots, translated to the E1 subchannel in cfg=B and
+cfg=C configurations (Tau/E1 only). 
+.It debug=0, debug=1, debug=2
+Turn on/off debug messages.
+.Ar 0
+- turn off debug messages.
+.Ar 1
+- turn on debug
+messages, equal to the
+.Ar debug
+option to the
+.Xr ifconfig 8
+utility.
+.Ar 2
+- high intensive debug message, developers only.

+- For Tau/G703 this mean one G703 channel and one digital channel.
+For Tau/E1 first physical channel divides on to subchannels. One of them
+goes to the first logical channel and another one goes to the second physical
+channel. Second (logical) channel is digital channel.
+.Ar cfg=C
+- This configuration is used only for E1 models. In this case first
+physical channel consists of three data flows. Two of them go to two
+(logical) channels. The last one goes to the second physical channel. On new
+models (Tau32-PCI, Tau-PCI/2E1 and Tau-PCI/4E1) this configuration means single source
+of synchronization and passing all unused (in both channels) timeslots from
+one channel to other. For the detailed description of the configuration see
+your documentation to the adapter. This option could not be set on running
+channel.
+.It loop=on, loop=off
+Turn on/off internal loopback. This mode is useful for testing. Switch on this
+option and try to send something. If you have no any interrupt, than, probably,
+you forgot to switch using IRQ for PCI to ISA bus. Check your BIOS settings.
+.It rloop=on, rloop=off (Only for Tau32-PCI and Tau-PCI/E3)
+Turn on/off remote loopback. This mode is also useful for testing.
+.It dpll=on, dpll=off
+Turn on/off digital phase locked loop mode (DPLL). When enabled, the receiver
+timing clock signal is derived from the received data. Must be used with NRZI
+encoding, to avoid the synchronization loss.
+.It nrzi=on, nrzi=off
+Turn on/off nrzi encoding. In off state nrz encoding is used. NRZ - the zero
+bit is transmitted by the zero signal level, the one bit - by the positive
+signal level. NRZI - the bit number zero is transmitted by the change of the
+signal level, the one bit - by the constant signal level. Commonly is used with
+dpll=on option.
+.It invclk=on, invclk=off
+Invert the both transmit and receive clock signals (Tau and Tau-PCI only).
+.It invrclk=on, invrclk=off
+Invert the receive clock signals (Tau-PCI only).
+.It invtclk=on, invtclk=off
+Invert the transmit clock signals (Tau-PCI only).
+.It higain=on, higain=off
+Turn on/off increasing the E1 receiver non linear sensitivity to -30 dB (E1
+only). In of state the sensitivity is -12 dB. This allows increasing line
+distance.
+.It cablen=on, cablen=off (Only for Tau-PCI/T3 and Tau-PCI/STS-1)
+Turn on/off adjusting transmit signal for long cable T3/STS-1.
+.It monitor=on, monitor=off
+Turn on/off increasing the E1 receiver lines sensitivity to -30 dB
+(Tau32-PCI, Tau-PCI/2E1 and Tau-PCI/4E1 only). This could be used for interception
+purposes.
+.It phony=on, phony=off
+Turn on/off the so-called phony mode (Tau32-PCI and Tau-PCI E1 family only). This mode allows
+receiving raw CEPT frames from E1 line. Raw frames could be accessed, for
+example, via raw protocol. Packets would come at rate of 500 frames per second
+with length 16xN (for Tau-PCI/E1 model), where N is the number of timeslots. For
+Tau-PCI/2E1 and Tau-PCI/4E1 N should be equal to 32 independently from number of
+used timeslots.
+.It unfram=on, unfram=off
+Turn on/off unframed mode (Tau32-PCI, Tau-PCI/2E1 and Tau-PCI/4E1 only).
+.Ar unfram=on
+switches channel to unframed G.703 mode.
+.Ar unfram=off
+switches channel to framed E1 (G.704 mode). 
+.It scrambler=on, scrambler=off
+Turn on/off the scrambling of G.703 data (Tau32-PCI, Tau-PCI/G.703 and Tau-PCI/2E1,
+Tau-PCI/4E1 in unframed mode only).
+.It use16=on, use16=off
+Turn on/off the usage of 16-th timeslot for data transmission (Tau32-PCI and Tau-PCI E1 family only).
+Normally 16-th timeslot is used for signaling information (multiframing CAS).
+.It crc4=on, crc4=off
+Turn on/off CRC4 superframe mode (E1 only). 
+.It syn=int, syn=rcv, syn=rcv0, syn=rcv1, syn=rcv2, sync=rcv3
+.Ar int
+- use an internal clock generator for G703 transmitter
+(clock master). 
+.Ar rcv
+- use the G703 receiver data clock as the transmit clock
+(clock slave). 
+.Ar rcv0, rcv1, rcv2, rcv3
+- use the G703 receiver clock of the other channel
+(E1 models only). 
+.It dir=<number>
+Binds logical channel to the physical channel (Tau32-PCI, Tau-PCI/2E1 and Tau-PCI/4E1
+only). Using this parameter you could, for example, split E1 physical channel
+into several channels.
+.It ts=interval
+Set up the list of timeslots to use by the channel (E1 only). The
+timeslots are numbered from 1 to 31, and are separated by comma or minus sign,
+giving an interval. For example: "ts=1-3,5,17". 
+.It pass=interval
+Set up the list of timeslots, translated to the E1 subchannel in cfg=B and
+cfg=C configurations (Tau/E1 only). 
+.It debug=0, debug=1, debug=2
+Turn on/off debug messages.
+.Ar 0
+- turn off debug messages.
+.Ar 1
+- turn on debug
+messages, equal to the
+.Ar debug
+option to the
+.Xr ifconfig 8
+utility.
+.Ar 2
+- high intensive debug message, developers only.
