- Granch SBNI12 leased line modem driver
driver provides support for leased line modems of following models:
SBNI12-05, SBNI12D-05, ISA and PCI
SBNI12-10, SBNI12D-10, ISA and PCI
and a kit for data link over a voice band:
SBNI12-11, SBNI12D-11, ISA and PCI.
In addition to the standard port and IRQ specifications, the
driver also supports a number of
which can set baud rate, receive level, and low three bytes of Ethernet
MAC-address (high three are always
because Granch modems are
presented to the system as Ethernet-like network cards.
The high byte of the
is a bit field, it is used to specify SBNI adapter receive level/baud rate:
- "Bits 0-3:"
receive level (0x00..0x0f)
- "Bits 4-5:"
baud rate number:
- "00 -"
0 baud rate (2Mb in fast mode/500kb in slow)
- "01 -"
1 baud rate (1Mb/250kb)
- "10 -"
2 baud rate (500kb/125kb)
- "11 -"
3 baud rate (250kb/62.5kb)
- "Bit 6:"
use fixed receive level
if bit 6 is set then receive level will be set according
to bits 0-3 value, otherwise receive level will be
- "Bit 7:"
use fixed baud rate
if bit 7 is set then baud rate will be set according to
bits 4-5 value, otherwise baud rate is set to 2Mb
