.Nd configuration utility for Granch SBNI16-SHDSL PCI modems
.Sh SYNOPSIS
.Nm
.Op Ar device_name
.Op Ar options
.Nm
.Ar device_name
.Op Fl R
.Sh DESCRIPTION
The
.Nm
utility is used for configuring the options of the SBNI16-SHDSL modems.
The options could be set only on inactive devices (the corresponding
network interface should be in down state).
.Ss "Mandatory parameters"
.Bl -tag -width 10n
.It master, slave
Set mode.
.It lrate=value
Set line rate. Value may be 64 to 4640 kbit/s increasing by 8.
.It tcpam32, tcpam16, tcpam8, tcpam4
Set line code.
.El
.Ss "Optional parameters"
.Bl -tag -width 10n
.It crc32, crc16
CRC length (default 32-bit).
.It fill_ff, fill_7e
Inter-frame space filling value: all '1' bits, or HDLC flag 0x7e (default
all '1'-es).
.It rboff
Turn PCI read burst mode off. May be useful with old motherboadrs.
.It wboff
Turn PCI write burst mode off.
.El
.Pp
If
.Nm
started without any option, device statistics will be printed. Flag
.Fl R
forces the driver to clear staticsic counters.
.Sh EXAMPLES
Configure modem:
.Bd -literal -offset indent
sb16config sbsh3 master lrate=2320 tcpam16
.Ed
.Pp
It needn't to reload the driver in order to change parameters. It's enough
to down the interface:
.Bd -literal -offset indent
ifconfig sbsh1 down
sb16config sbsh1 tcpam8 slave lrate=96
ifconfig sbsh1 inet 192.168.10.25 netmask 0xffffffc0
.Ed
.Pp
Print modem statistics:
.Bd -literal -offset indent
sb16config sbsh0
.Ed
.Pp
Clear modem statistics:
.Bd -literal -offset indent
sb16config sbsh0 -R
.Ed
