31 .Nd Granch SBNI12 leased line modem driver
33 .Cd "device sbni0 at isa? port 0x210 irq 5"
34 .Cd "device sbni1 at isa? port 0x2c0 irq 11 flags 0xe9123456"
38 driver provides support for leased line modems of following models:
41 .It Pa SBNI12-02, SBNI12D-02
42 .It Pa SBNI12-04, SBNI12D-04
43 .It Pa SBNI12-05, SBNI12D-05, ISA and PCI
44 .It Pa SBNI12-10, SBNI12D-10, ISA and PCI
47 and a kit for data link over a voice band
48 SBNI12-11, SBNI12D-11, ISA and PCI.
50 In addition to the standard port and irq specifications, the
52 driver also supports a number of
54 which can set baud rate, receive level, and low three bytes of Ethernet
55 MAC-address (high three always are 00:ff:01), because Granch modems is
56 presented to the system as Ethernet-like netcards.
60 is a bit field, it's used to specify SBNI adapter receive level/baud rate:
62 Bits 0-3: receive level (0x00..0x0f)
63 Bits 4-5: baud rate number:
64 00 - 0 baud rate (2Mb in fast mode/500kb in slow)
65 01 - 1 baud rate (1Mb/250kb)
66 10 - 2 baud rate (500kb/125kb)
67 11 - 3 baud rate (250kb/62.5kb)
68 Bit 6 : use fixed receive level
69 if bit 6 is set then receive level will be set according
70 to bits 0-3 value, otherwise receive level will be
72 Bit 7 : use fixed baud rate
73 if bit 7 is set then baud rate will be set according to
74 bits 4-5 value, otherwise baud rate is set to 2Mb
77 device sbni0 at isa? port 0x210 irq 5 flags 0xefdead
78 - baud rate 2 Mb (default), receive level autodetected,
79 MAC address will be 00:ff:01:ef:de:ad
81 device sbni1 at isa? port 0x214 irq 7 flags 0xd6abcdef
82 - baud rate 1 Mb, receive level 0x06 (fixed),
83 MAC address 00:ff:01:ab:cd:ef

99 device driver first appeared in
104 device driver for FreeBSD 4.x was written by Denis I. Timofeev, partially
105 based on David Greenman's
107 driver. Earlier versions (available on ftp.granch.com) were written by
110 SBNI12 hardware was designed by Alexey V. Chirkov.
