LabelDescription

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:

Range of

Values:

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

The range of values that may be assigned to the register is explained following this label. The units for the value may be as follows:

decimal—a one- to three-digit decimal number. Decimal numbers are typically used to represent a count, seconds, or fractions of a second.

ASCII—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").

hexadecimal—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).

2 . 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).
