Modem Reference

6-25

Specifies the lowest bit rate at which the

modem may establish a connection. (This value

is fixed at zero for the EtherExpress™ PRO/

100 LAN/Modem PC Card Adapter.)

Specifies the highest bit rate at which the

modem may establish a connection. For

modulations that support only a fixed bit rate

(such as V.22bis), has a fixed value

to which it defaults. If the default rate or a rate

other than zero is specified, the modem will

return ERROR. This subparameter accepts the

following values: 0, 300, 1200, 2400, 4800, 7200,

9600, 12000, 14400, 16800, 19200, 21600,

24000, 31200, 33600bps. If unspecified (set to

0), is determined by the value of

.

If the setting is K56, the

subparameter should be left at the default value

(zero).

S-Register Reference

This section provides information on all the S-Registers supported by the

Intel EtherExpress™ PRO/100 LAN/Modem PC Card Adapter. It is

divided into two parts:

• Introduction to S-Registers
• S-Register Reference (in numerical order)

Introduction to S-Registers

The Intel EtherExpress™ PRO/100 LAN/Modem PC Card Adapter uses

memory storage locations, or S-Registers, to hold information controlling

its operating environment. Few of these S-Registers require attention from

modem users.

Some of the S-Registers are reserved. These either contain parameter bit

maps for the internal use of the modem or are not in current use. Gener-

ally, modem users should not alter or write to any of these reserved
