-.Dt SCONFIG 8
-.Os FreeBSD
-.Sh NAME
-.Nm sconfig
-.Nd channel configuration utility for Cronyx adapters
-.Sh SYNOPSIS
-.Nm
-.Op Fl aimsxeftuc
-.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 e
-,
-.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
-have no any interrupts, than you use interrupt that is not registered in BIOS
-for use with ISA bus.
-.It Fl x
-Print full channel statistics. This options allows to see some more counters,
-but with less precision than with
-.Pa -s
-option.
-.It Fl e
-Print brief E1/G703 statistics. If you select this option, you will get
-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
-Print brief E3/T3/STS-1 statistics. If you select this option, you will
-get statistics accumulated for period of time equal to 15 minutes. For
-the description of output, see below.
-.It Fl u
-Print full E3/T3/STS-1 statistics. This option shows all E3/T3/STS-1
-statistics that shows previous option(
-.Fl t
-), 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 c
-Cleans all kind of statistics. 
-.El
-.\"--------------------------------------------------------------
-.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.
