-.Nd channel options management utility for Cronyx-Sigma adapter
-.Sh SYNOPSIS
-.Nm
-.Op Fl a
-.Op Ar <channel> Op Ar <option>...
-.Sh DESCRIPTION
-The
-.Nm
-utility is used for configuring the channel options of
-the Cronyx-Sigma adapter.
-.Pp
-To change channel options the channel should be free: the corresponding
-network interface in ``down'' state, the asynchronous terminal device
-.Pa /dev/tty*
-closed.
-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.
-.Pp
-The following option is available:
-.Bl -tag -width indent
-.It Fl a
-Display full information.
-.El
-.Sh "Channel options"
-.Bl -tag -width 10n
-.It ispeed=#
-Set the receiver baud rate to the number given.
-The maximal value is 256000 bits/sec.
-In the synchronous mode the receiver baud rate is significant
-only when DPLL mode is used.
-.It ospeed=#
-Set the transmitter baud rate to the number given.
-The maximal value is 256000 bits/sec.
-In the synchronous mode the transmitter baud rate is significant
-only in the case of the internal clock source.
-If receiver and transmitter have equal data rate, then it could
-be set by specifying only the numerical argument.
-.It async
-Set the asynchronous channel mode.
-.It "hdlc, bisync, bsc, x.21, x21
-Set the synchronous channel mode: HDLC, Bisync (BSC) or X.21.
-.It ppp
-Set the link-level protocol: PpP/HDLC.  The built-in simplified synchronous PPP
-implementation is used (see RFC-1548, RFC-1549).
-.It cisco
-Set the link-level protocol: Cisco/HDLC (see RFC-1547).
-This protocol is intended for compatibility with old models of Cisco routers,
-and with early versions of
-.Tn BSD/386
-drivers.
-The extensive usage of this protocol is not recommended.
-.It ext
-Use the external link-level protocol suite (for
-.Tn BSD/386
-only).
-.It "+keepalive, -keepalive"
-Enable the automatic line state control sub-protocol.
-This setting is not significant when the external link-level protocol is used.
-.It "+autorts, -autorts"
-Enable the automatic RTS signal control.
-When enabled, the RTS signal goes up only when both halves of
-the receiver ring buffer are free and ready for receive,
-and goes down when one or both buffers are busy.
-.It "port=rs232, port=rs449, port=v35
-Set the zero channel hardware interface type.
-.El
-.Sh "Common options"
-.Bl -tag -width 10n
-.It "nrz, nrzi, manchester"
-Set the data line signal encoding.
-In the case of
-.Em NRZ
-encoding the zero bit is transmitted by the zero signal
-level, the one bit - by the positive signal level.
-In the case of
-.Em NRZI
-encoding the zero bit is transmitted by the change of
-the signal level, the one bit - by the constant signal level.
-In the case of
-.Em Manchester
-encoding the zero bit is encoded as 01 value,
-the one bit - as 10 value.
-.It "+dpll, -dpll"
-Enable the digital phase locked loop mode (DPLL).
-When enabled, the receiver timing clock signal
-is derived from the received data.
-.It "+lloop, -lloop"
-Set the local loopback mode.
-.It "+extclock, -extclock"
-Set the timing clock source of synchronous channels.  There are
-two possible variants:
-.Em "external clock"
-source or
-.Em "internal clock"
-generation.
-.Pp
-.Em "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).
-.Pp
-In the case of
-.Em "internal clock"
-mode 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 fifo=#
-FIFO threshold level setup for receiver and transmitter.
-.It rfifo=#
-Hardware RTS/CTS flow control FIFO threshold setup.
-.It "+ctsup, -ctsup"
-Enable/disable interrupts on CTS (Clear To Send) signal setup (0 to 1 transition).
-.It "+ctsdown, -ctsdown"
-Enable/disable interrupts on CTS (Clear To Send) signal clear (1 to 0 transition).
-.It "+cdup, -cdup"
-Enable/disable interrupts on CD (Carrier Detect) signal setup (0 to 1 transition).
-.It "+cddown, -cddown"
-Enable/disable interrupts on CD (Carrier Detect) signal clear (1 to 0 transition).
-.It "+dsrup, -dsrup"
-Enable/disable interrupts on DSR (Data Set Ready) signal setup (0 to 1 transition).
-.It "+dsrdown, -dsrdown"
-Enable/disable interrupts on DSR (Data Set Ready) signal clear (1 to 0 transition).
