DESCRIPTIONThe driver provides support for leased line modems of following models:
- SBNI12-02, SBNI12D-02
- SBNI12-04, SBNI12D-04
- 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 flags which can set baud rate, receive level, and low three bytes of Ethernet MAC-address (high three are always 00:ff:01 ) because Granch modems are presented to the system as Ethernet-like network cards.
The high byte of the flags 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 autodetected
- "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
