Description

Register:

The S-register is identified following this label. Note that the names

for S-registers 1 through 9 may be typed as two-digit numbers with
leading zeros, if desired, for readability (e.g., S01 is equivalent to S1).

Description:

The purpose and use for the S-register is explained following this
label.

Range of

The range of values that may be assigned to the register is explained

Values:

following this label. The units for the value may be as follows:

decimal

ASCII

hexadecimal

—a one- to three-digit decimal number. Decimal numbers

are typically used to represent a count, seconds, or fractions of a
second.

—a one- to three-digit decimal number that represents the

decimal equivalent for an ASCII character (see ASCII Character
Table in Appendix D, "Quick-Reference Summaries").

—a two-digit hexadecimal number used to represent

the contents of a bit-mapped S-register. Bit-mapped S-registers are
not usually set by entering a complete value for the register, but are
set one or more bits at a time by various AT commands.
Hexadecimal digits include the decimal digits 0 through 9, and the

letters A through F.

Notes:

1.

A value typed as a decimal or ASCII argument
to a command may be entered as a one, two, or
three digit number, as required, but will always
be displayed as a three digit number (for
example, you type the command

ATS0=3

to set

automatic answer feature to answer an incoming
call on the third ring, and then type the

AT&V

command to verify the value, which is displayed
as

S00:003).

The

&V

command, which displays the contents

of all S-registers, presents the contents of bit-
mapped registers as two hexadecimal digits

followed by an uppercase letter

H

(for example,

assuming that S-register S14 contains the value

AA hexadecimal, the

AT&V

command displays

S14:AAH).
